Help with usb performance

USB Performance will vary considerably with different devices on different systems. Here's a couple of things you should check:

1 - Is the cable a USB 2.0 compliant cable?
2 - Check BIOS settings to ensure that 'Hi Speed/USB 2.0) is enabled.

Let us know if either of those things corrects your problem.

Your motherboard is USB 2.0 compliant, it should work fine and may simply be set to slow speed in your BIOS.

i checked the bois settings evertythinhs fine there. but the speed is still low
when i start copying something the speed starts at about 600 kbytes/sec and then gradually increses upto 13-14. but it takes a lotta time for the speed to increase

What is it that you are copying to? I have very slow speeds copying to memory cards & mobile phones (via USB) but i get a constant 23MB/s from my external HD.

I'm having the same problem.

USB 2.0 is enabled in the BIOS, no conflictcs/alerts in my device manager.

Speeds were fine with XP, so it's not a hardware issue.

REALLY frustrating, been trying to solve this for a few hours now

I also have problems using USB flash (pen) drives. Performance is extremely slow to the point where the device itself hangs. This occurs when I browse, copy or move files and folders to/from the device. The only solution is to unplug the the device from the USB port.

I don't experience any problems with USB devices in Windows XP. Vista on the other hand, is a bit of a gamble -- sometimes it works, sometimes it just goes mad... I've tried changing the BIOS settings, but to no avail. Vista/Win7 hates my USB flash drives, or so it seems. I was hoping Win7 would fix the USB issues I was getting in Vista. Unfortunately, this has not happened. If anything, my USB woes have gotten worse in Windows 7. At least with Vista, I was able to use my flash drives from time to time.

Have you tried to format the drives in Windows7 just to see if there is some type of bad block that is slowing it down. If you format it will create a table so windows wont write to bad parts of the drive. Also running a scandisk on it would help see if there is a physical problem with the memory on the device.

I'm not sure about the threadstarter, but my problem is not limited to any single device.

2 flash drives, external harddrive, iPod, iPhone, all interact with the computer at painfully slow speeds.
