Hi Greg, All.
One of my computers has a USB interface plugged into the PCI bus, and it
appears to be unsupported by Linux. Can anybody here advise please?
Here's what I can tell you about this beastie:

The kernel in use is RedHat's 2.2.14-12 kernel as the 2.2.20 kernel
recently released is unstable on this machine, and it doesn't have
enough RAM for any of the 2.4 series kernels.
Comments, anybody?
Best wishes from Riley.
