There are alot of USB 2 cards for the PCI bus out there, not for ISA.
They all "work" but your mileage may vary...
Your CPU processor speed and bus timing may be too slow to keep up with
the net throughput (effective speed end to end) even after you add the
new card. I had a Pentium 4 (500Mhz) with a PC100 memory bus with a USB
2 card added to it's PCI bus. Some GnuRadio applications worked great,
many did not. It really was below spec of what many people had
reportedly used in these applications.
...and it was still great fun to experiment with!

We have a guy trying get his computer to talk to a USRP. Unfortunately
his computer only has USB 1.1 ports. Does anyone have any experience
using a cheap USB2.0 card in such a PC? We are thinking of running out
and grabbing a card and trying it.
Thanks,
