I have had no problem with my Linksys 10baseT usb adapter. Running winblows 98.
Original Bios
isa ide/parallel/serial card
QuickCd Parallel on LPT2 (WebSurfer port)
updated video driver
updated audio driver
Pci bridge driver
10gb western digital (Master)
4x Create Labs (Slave)
48mb Ram
All I did was enable USB support in the Bios.
Biggest transfer so far 30mb. Lot's of web activity via internal network with no problems. Acutally Websurfer is more stable than my other pc's at this point :).
