I have this wonderful system built around a P4P800 Deluxe.

It works perfectly, including all USB 2.0 devices I have connected to
it so far:
* Cruzer Mini USB drive (256MB)
* Samsun Digimax 201 camera
* EPSON Perfection 3200 scanner

However, when I connect the scanner through the switch, the scanner
becomes an "Unknown device". This problem does *not* occur on a
different PC running Windows XP and using the same exact switch and
scanner (that's why I bought the switch, so that I can share the
scanner between two PCs ).

Since I am using W2K-SP4 with all latest updates, and the date/version
on the USB2 driver is later than the one the came with the P4P800
Deluxe CD, I did not install the driver that came with the CD. That
decision seemed to be correct, but having this strange problem I am
not sure anymore...

The following is a date/version comparison between the ASUS P4P800
Deluxe CD and what's currently installed in my system:

File ASUS P4P800 Deluxe CD W2K-SP4 (installed)
------- --------------------- -------------------
usbhub20.sys 2002/4/17, 5.0.2195.5605 2003/6/19, 5.0.2195.6717
usbport.sys 2002/4/22, 5.0.2195.5652 2003/6/19, 5.0.2195.6681
usbehci.sys 2002/4/22, 5.0.2195.5652 2003/6/19, 5.0.2195.6709

Which is newer? Are there even newer W2K drivers in existence?

The P4P800 Deluxe CD also came with 3 more files that I cannot find in
my system:
* hccoin.dll
* ich5usb2_win2k.inf
* usb2.cat

What do you think? Am I using the latest and greatest? If not, what is
the latest and greatest?

Thank you!
Daniel
