This old Pavilion I'm using to network a printer and storage has only two USB 1 ports.
Having a nearly equally old PCI usb2 4 port card I thought no probs!

But the wireless USB adaptor wont work on the PCI card,, runs fine on the usb1 port(at 55kbs) but not even a power light when plugged into the card.

we are talking old here,,, the PSU is 70W's,,,,,

oh, and the system sees the Hi speed hub,,

using Xp Pro,,
