Can you try either the patch at:
	http://marc.theaimsgroup.com/?l=linux-usb-devel&m=101588420909194

Or just renaming your usbmodules binary to something else and see if the
problem goes away?

The USB initialization timing changed between 2.4.19-pre1 and -pre2,
fixing a lot of problems with devices that had previously not worked on
Linux, but worked fine on Windows.  Turned out we were wrong on the
timing issues :)

Let me know if this helps or not.

thanks,
