Hi to all community,
I report thi problem:
using win 2000, I have installed a card USB2.0 by trust.
Work properly.

Then I connected to one USB2.0 an external case box, containing an hard disk.

All ok.

But when I trasnsfer data, is extremely low!!!, working as an usb 1.0

So I try fixing with the service pack 4.0.
It's the same: slow.

I really can't understand why it goes like that, bacuuse all the periferals are ok and doeasn't report any error.

Any idea?!

thank you.

Open Device Manager, click the + button next to Universal Serial Bus Controllers. Look at the lines underneath..... Do you see the word Enhanced in any line? If not then you either don't have a usb 2.0 controller or you don't have the proper drivers/service packs installed.

copy and paste the lines you have under USB, repost results back here.
