USB 2.0 very slow - Windows XP Pro

Hello,

My USB 2.0 speeds are very slow. I have been copying from an external 2.5" drive to my PC and it took about 30 mins to copy a 700MB file.

I thought realistic speeds for USB 2.0 was up to 40MBps? The above speed seems to be about 3mbps.

I was only transferring one file at the time. I have one other usb device attached but that was switched off.

Any ideas where to start?
 
Perhaps the USB stick is a 1.1 device? have you tried using the USB ports on the I/O panel? Those adapters you get to replace a floppy or something are generally slower.

It's an external hard drive so it shouldn't be 1.1. I've also tried my friend's which he says is fast on his PC

I've tried the front USB's which connect to the motherboard. Is that what ou mean? Or do you mean the ones on the back?
 
ok, tried the USB ports at the back and I get seemingly normaly speeds. I copied about 800MB in about 40 secs. Which is about 100 times faster than before.

So why are the front ones so slow? How do I get them going fast?
 
Front USB = 1.1 USB....you can have a USB drive with USB 5.0 and 100mb transfer speeds but its worthless without a USB on your board that also is 5.0. (mind you only 3.0 so far is out )

Also the front USB are from the CASE not the motherboard thus the difference in speeds.

Don't the front USB's plug directly into the motherboard? Do they connect to a different bus?

Why would anyone make a motherboard with USB 1.1 these days?




Here's my setup:

Gigabyte GA-EP45-UD3R motherboard
4GB RAM
E7500 Duo
 
I don't know, but my case has 4x USB ports on the front and they are all at good speeds, but my brothers thumbdrive is horribly slow - it's a 1.1 drive. he got it in a cheap store and they advertised it as a 2.0 drive
