You might be better off asking on the linux-usb-users list, but if you
believe that the USB disk and enclosure are healthy then it could be
something as simple as the USB cable not being less than brilliant.
Have you tried a different one? Different port? Different machine?
I may be mis-remembering, but I seem to remember from the RHEL3 release
notes that USB disks aren't supported. I do know that the stock
ehci-hcd driver in the 2.4 series kernel is not exactly good, but I
don't know what was back-ported to the RHEL3 kernel and what the later
release notes say about USB disk support. And it's quite possible I'm
talking absolute tosh.
