Usb Speed - Same Transfer Rate From Usb 2.0 And Usb 1.1


I have a usb2 1gb thumbdrive. I have 4 usb2. 0 ports on the back of my computer and 2 usb1. 1 ports on the front of my computer. When i plug my thumbdrive into the front or back i get the same transfer rate. Now i'm sure that's not suppose to happen. In my device manager i have, under universal serial bus controllers, intel(r) 82801eb usb universal host controller, have 4 of those, then i have one of, intel(r) 82801eb usb2 enchanced host controller. Any suggestions? I have xppro sp2.

Difference In Transfer Rate From Usb To Usb And Hdd To Usb

I have an seagate 160gb external hdd (fat32), and i was wondering if moving the page file to the external disk would garner any extra performance gains. I was also wondering if there is a difference in the transer rate from the usb->usb and hdd->usb. I was thinking about using hdtach on my external drive, so i think i'll give that a try.

What's A Good Transfer Rate For Usb 2.0 External Hdd ?

Just curious what a good transfer rate when transferring from the external drive -> internal drive via usb 2. 0 connection. I was getting 22. 5 mb/s according to vista when transferring from my external 5400rpm laptop hdd to my internal 7200rpm laptop hdd. Is that a good rate?

Hdd Transfer Speed Over Usb

I keep on wondering how come my hard drives have such a low transfer speed with usb. I have a mybook and a usb docking station. Both of them cannot transfer past than 20mbs. When i switch back to sata, i get at least 3 times the transfer speed (more for my faster drives). Sata is faster than usb, i can understand that. But usb 2. 0's rated transfer rate is 60mbs, what exactly is throttling the speed?

Transfer Speed On Usb Is Very Slow - Seagate 160 Gb Hd

I am having couple of problems with my trasnfer speed. I just bought a new enclosure case for my seagate 160gb hd. I am finding the transfer speed is very slow compared to anthoer enclosure case i have containing 20gb hd. My pc has usb 2. 0. On my old case, i get a speed of about 23 mb/sec majority of times. My new case is only giving me about 15 mb/sec. What can i do and how do i make it faster? I even exchanged the two hd to see if it is the hd that is causing it to be slow, but i found out it is the enclourse case. When i put the 160gb hd in the old case, it transfers at 23 mb/sec.

Best Way To Get Max File Transfer Speed (network, Usb, Etc)

I use a laptop for my main rig (hp dv8300), and i am setting up a nas in the near future and i'm trying to come up with the best way i can get the most speed to dump data to it. It's a 945gm express chipset. I have usb 2. 0, firewire of some flavor (i can't figure out which one it is), pci card slot, express/54 card slot, 100mb nic, intel something b/g mini pci nic. Ideally i would want to get a 1000mbps nic, but since my nic is onboard i can't really swap it out. A 1000mbps usb 2. 0 nic would still limit me to the 300mbps speed of usb 2. 0. 132 mbps for express card. Right now my best idea is just to get a wirless-n mimo mini pci nic and swap it in. Unless someone has a better idea.

Dell I9200 Laptop Usb Ports Are All Normal Speed Not Usb 2.0

I purchased a refurbished dell ( inspiron ) i9200 laptop a few months ago, haven't used any 2. 0 devices until last week, when i plug it in it says my ports are all normal speed, however i know they're supposed to be 2. 0. I can't seem to find drivers or anything that will make them 2. 0. And dell won't talk to me because i didn't buy it new from them i bought it from a certified reseller. Any ideas on what to do?

Usb Message: Hi-speed Device Plugged Into A Not Hi-speed Port

I'm rebuilding my system, and have two pci cards with firewire and usb ports. I remember before the rebuild i plugged them in and they worked. That was nice. Now, i installed them one at a time. The first one prompted no notifications, but when i plugged a device into it it warned me that it was a hi-speed device plugged into a not hi-speed port. I installed the second one, and it prompted the new hardware wizard, asking for drivers, but said it couldn't find them although i had dsl connected. The cards did not come with any disks and there was no problem getting them to work before.

Very Slow Usb Transfer / Detection

I have asus m3n78-vm mobo and it has some problems in it. I think my usb ports are not running as fast as they can. When starting windows it takes ages to detect my external hdd , buffalo drivestation 500gb usb 2, and transferring like 300 mb file from internal hdd to that external is pain in the ass slow. Transferring from external to internal it has no problems. Files fly from buffalo to my internal sata hdd. But if i try to move file from that internal hdd to external buffalo, windows says it takes about 10 minutes to transfer one 300 mb file and it does also take that long, so what a heck? Im confused. I checked bios and all usb 2 features are on in bios. I also had some weird io shutdown problems. Anyone has any solutions to this? My buffalo also has some turbousb feature but dunno if it works. Oh and i use 32 bit xp pro with sp3 in it. Btw my old mobo dfi lanpary nf3 ultra-d did not have this problem with my external hdds. I have also tried all usb ports, and its the same problem.

Changing Usb Polling Rate To 1000hz Or Lower

If your like me and hate default 125hz that all windows install (unless you modify) here is a quick way to change your usb polling rate to 1000hz (1. 00ms response time). Note: some mouses don't go all the way up to 1000hz. This is mainly in wireless mouses. Windows vista & 7 64-bit:-

1. What you need: hidusbf.zip - dimr.exe (direct input mouse rate). 2. Extract hidusbf.zip & dimr.exe into a folder. 3. Right click on "hidusbf. Inf" find install (if warning comes up about unsigned drivers don't worry). 4. Open up dseo13b.exe and check "enable test mode". 5. Reboot. 6. After reboot you will see "test mode windows xxxx build xxxx" you can get rid of this but for now reopen dseo13b.exe and check "sign a system file". 7. In the box type in "c:windowssystem32drivershidusbf.sys". If correct a window will come up saying "the system file has been signed succesfully. ". 8. Reboot. 9. Reopen hidusbf folder and click on "setup.exe". 10. Find your mouse click on it (it should be highlighted has blue) and at the bottom of the window check "filter on device" and select your rate. 11. Click restart and open up dimr.exe. If it's still runs default 125hz reboot your windows vista or 7 64-bit operating system again. 12. To remove watermark open dseo13b.exe and click on remove watermarks. It will link you to the website with the correct files to remove it. Windows xp/vista/7 32-bit:-

1. Right click on "hidusbf. Inf" find install, (note sometimes with xp if you apply and the mouse stops responding in this case restart again and try again). 2. Open hidusbf folder and click on "setup.exe". 3. Find your mouse click on it (it should be highlighted has blue) and at the bottom of the window check "filter on device" and select your rate. 4. Click restart and open up dimr.exe. If it's still runs default 125hz reboot.

Can't Do Anything Else When Transfer A Large File Using Usb

So i've been running x64 for the better part of a year now on the rig in my specs. Within the last 3 months or so if i transfer a large file to any one of my various brand external hard drives i can't really do anything else on my computer, everything kinda just slows down and the usb transfer takes precedence. The strange part is my cpu usage is only like 5-15% on a single core while this is going on. I know i should most likely nuke my os install and start over but i'm curious as to what caused this. In my many years of pc tech support i have not ran into this particular issue. I have seen similar caused from crappy via usb controllers but not this exact problem. Ideas?

Mouse Dpi And Usb Polling Rate - Knowledge Base

Just thought id share with you some knowledge on the subject of (usb) mouse polling rates and how they can affect your online gaming (well, they wouldnt affect anyone elses now would they). Windows xp, being pretty trashy as it is, by default sets the windows usb polling rate at 125mhz thats an 8ms response time to me and you. What does this mean, well, this equates to lag! The bane of all counterstrike and alike players, and generally all good fps games. Now, what can we do about this, well, interestingly enough we can, depending on the quality of your usb mouse (i have a razer diamondback) you can increase the responsiveness significantly. The basics are, the polling rate determins the time it takes for an action performed on the mouse to be transmitted to your computer and thusly to the game/software your using, so this incorporates a slight delay (lag) into your responses within the game. This becomes more prenounced while playing online games where pings/latencies and rates also effect your lag or responsivness. This can mean the difference between a shotty between the eyes and getting that "god-like" voice sounding off in the background

Is i stated earlier the default polling rate is 125mhz (8ms) and so naturally we get quite used to this when playing games, but wouldnt it be far greater to eliminate as best as possible this delay in sending mouse commands to your games to give a more fluid and responsive control over your gaming? Id say *** yeah!

Right, there are a few different ranges you can use, and all are totally dependant upon your mouse's abilities, but none should harm your mouse (best have a ps2 mouse at hand incase yours aint up for the higher rate so u can change back to default), firstly: we have:-

125mhz @8ms response time (default)

250mhz @4ms response time

500mhz @2ms response time

And the highest so far:

1000mhz @**1ms** response time!

Right, i currently use a razer diamondback usb mouse, and have the polling rate set for 1000mhz, the actual polling rate is often fractionally lower than stated but pretty damn good. I have personally noticed improvements in the sensitivity and responsivness in my mouse, especially when playing online fps games. But there is an improvement to be had when playing singleplayer fps games and other games alike. I am providing a link to the software i used to patch my usb polling rate, and included is also a mouse polling rate detector to tell you your current response time. See the screenies. Just a note though. Once you change your polling rate you must restart windows for the changes to take affect. This can make games more enjoyable especially the online games, but it could also be that you just dont notice the difference, as in the case that your mouse only supports a marginally higher response time. But anything which reduces the amount of lag gamers suffer can only be a good thing. I will amend the post if i have missed something, but i think i got everything on here. As you can see from the screen shot the razer diamondback performs very well, often over 1000mhz, less than 1ms, but on average its more like between 700-900mhz, still a damn good improvement over 125. Here is a link to both the current mouse polling rate detector and the usb polling rate patch, neither created by me so i claim no glory here, other than i zipped them together in one handy package.

How To Increase Usb Sample Rate In Windows Vista Sp1 ?

Microsoft windows vista’s default 125hz usb sample rate is not enough for today’s gamers and end-users. There are many usb sample rate patches out there, but none of them are supporting windows vista sp1 - due to the new restricted driver signature enforcement feature. However, it is now possible to use these patches thanks to the latest version of our own driver signature enforcement overrider (dseo), but i am not taking any responsibilities for any damages! Use it at your own risk. 1. Download driver signature enforcement overrider (attached below). 2. Download hidusbf (attached below). 3. Run driver signature enforcement overrider and choose enable test mode. 4. Extract hidusbf to some folder, right click on hidusbf. Inf and choose install. 5. Run setup.exe from hidusbf’s folder, check the filter on device box and select your desired sample rate. 6. Run driver signature enforcement overrider again, choose sign a system file and insert full path to the installed hidusbf.sys file (usually c:windowssystem32drivershidusbf.sys). 7. Restart your computer and enjoy. 8. Verify by using mouse rate or directinput mouse rate (attached below)

That should do the trick. Remember! Use it at your own risk! Do not blame me if your motherboard explodes, vista or usb fails. But, i have already tested it myself with a lot of success, so you don't have any reason to worry. If you would like to uninstall it, just right click on hidusbfu. Inf, choose install and disable test mode from driver signature enforcement overrider.

Usb Transfer Files Won't Read

Everytime i transfer files to my usb like ms word document, pictures, and music. The file won't read! Why is this happening? For instance, if i try to open the picture i saved, all i got is a "mini x" and if i try to play music it won't play either. Next, i created folders with some documents inside it. If i try to open that folder, there is no file displayed. At first, i thought it was a bunch of hidden files. So i tried to change the settings to make invisible files visible. No luck. My files are nowhere to be found! If i try to delete it, i got an error message " cannot delete file. "

Note: i did error checking and also tried reformatting it. Unfortunately, its still not working. It still has a problem with reading/opening files. Worse, some of my files are freaking' hidden( despite making invisible folders visible)

Some additional info about the usb i'm using. 1gb kingston
Type:removable disk
Filesystem: fat32

Usb Drive Wont Work After Unplugging It During File Transfer

I gave this usb flash drive to a friend as a gift http://www.Supertalent.com/products/stt_usb_detail.php

Its the 8gb pico usb drive, ive had one for over a year and ive had no problems but my friends wont work after he told me he accidentally unplugged it during a file transfer on his mac. If i plug it in to a mac it wont see the drive, not even the disk utility. If it plug it in to a vista machine, it gets seen but it says "unknown device" and it wont show up under disk management either. Is there any possible way to fix it? This is a first for me since i thought you could not damage usb drives if you unplugged them during a file transfer (except for normal data corruption). Any ideas?

Usb Port Speed Identifying Program

My asus p5q should have usb 2. 0 ports, at least all of the 6 on the rear panel, but using some with my linksys wusb54g makes winxp give me *** about not being 2. 0 ports and how i should check the list to use another. However it's not east to tell which ports are which. It would be cool if there was a program which presented usb ports and devices in a hierarchy, visually and showed you what was where. Or at the very least, i need something that spells out very clearly which ports are 1. 1 and which are 2. 0 just seeing an "enhanced" controller isn't helping.

How Can I Tell If My Usb Ports Are Regular Or High Speed ?

How can i tell if my usb ports are regular or high speed? I have 4 ports off the mobo, 2 ports off the mobo in the front of my case and an add on pci card of 4 more usbs. Os is xp pro with sp2. When i look in device manager i see a lot of usb ports/hubs. I hooked up an ipod the other day and it told me i didn't have any usb high speed ports. I reinstalled the drivers for the belkin pci card and that seemed to make the pci card's ports happy with 2. 0, do these drivers work on the mobo's usb ports too? I thought xp would take care of the mobo's ports and make them 2. 0.

Usb Flash Drive Speed Is Very Slow

I need a larger usb flash drive and was wondering what people would suggest. I have a 4gb drive now, but need something bigger. I have noticed that the transfer rate to my drive is very slow and was wondering if that has to do with the usb technology or because of my drive. I'd like one that transfers as fast as possible, but if they all transfer at the same speed, then so be it.

Usb Isn't Running At 2.0 Speed

I'm currently running an athlon x2 6000+, msi k9a2 platinum ver 1 mobo, raptor, 3gb ddr2-800, vista 64 and i know my usb isn't running at 2. 0 speeds. I've uninstalled and reinstalled drivers, checked cables, even went it and saw it said usb enhanced, but that's only in one part. When i plug in devices that are usb 2. 0 capable, it says plug into a usb port with 2. 0 for faster speeds. I'm so lost. I'm tired of uploading 2gb of photos or updating my iphone, only to wait up to 30 minutes for transfers. I have read and searched so many websites for help, but i can't find a way to fix it.

Device Can Perform Faster If Connected To Hi Speed Usb 2.0 Port

Every day, a bubble that says the following pops up "this device can perform faster. This usb device can perform faster if you connect it to a hi-speed usb 2. 0 port. For a list of available ports, click here. " It pops up even when there are no usbs in my computer. It happens close to 50 times a day and is bugging me. If i click on it there is a check box that says "notify if device can perform faster" and i uncheck it and click close and then a few seconds later it pops up again. It is very annoying because every time it pops up it makes this "boop boop" noise and when i try to listen to music or watch a video the sounds disrupts it. I have an hp pavillion dx6000 laptop running windows vista. Please, if anyone knows how to solve this, let me know.

Alcatel Speed Touch Usb Cause High Pitched Sound From Mobo

When i plug in my usb alcatel speedtouch usb modem, a very high pitched sound comes from the mobo, it is then and only then when this sound is produced. As long as the modem is plugged in and operating the sound is alive. It dies as soon as i plug out the modem. There is nothing else wrong, only this really annoying sound. I have two theories. 1)my psu is of low quality and that causes the problem (i own 400watt psu kinda no name, it's called pegasus) 2)the mobo is faulty. I dont want to go and rma the mombo if something else is wrong. Ps1:the usb alcatel speedtouch is known for it's power problems cause it drains 500ma, but with my previous motherboard and supply (a7n8x deluxe revision 1. 04 and psu 350) nothing bad ever happened. Ps2:i have connected one sata 120gb hdd (western digital. Jd model), 1 nec 3500a dvd-rw and asus 9600xt graphics card. Ps3:i have tried bioses 1005 and 1006, o/c and non-o/c cpu and mem, nothing works.
