USB 2.0 full speed instead of hi speed

[Monty Burns]

Okay, this is the problem:

A friend of mine lately decided to get his 2 computers in a network.
As he only needs to transfer data between them he decided to get a usb 2.0 link cable
from anubis (typhoon).
One computer has a k7vt2 (asrock) mobo with onboard usb 2.0 ports (via) which seem to be properly installed and it uses win xp prof. sp1a.
The other one (ecs k7vza 3.0) has a pci usb 2.0 card built in (also via chipset ), with win2k sp4.

The software (super link) which came with the data link cable also is properly installed.

The actual problem is that this software shows one computer (win2k) is running only on full speed, while the other is on hi speed.

It seems to be impossible to install the via 2.0 driver on the win2k machine, cos device manager only shows a usb 2.0 root hub, but not a via enhanced usb 2.0 controller (like on the win xp machine).

I have tried almost everything now to help him, but I cannot figure it out.
At least,after installing the via usb filter driver the system doesn't hang / crash anymore, but data transfer speed is really sh**, well it could be better.

Does anybody have a solution ?
