Hi there.
As a followup to Kjeld Jensen's posting, I did some testing with my
QDI USBDisk that arrived today. It is a flash ROM device with 64 MB
capacity (in my case, there are others). The device is found by
Windows, and is working there.
The device is detected and claimed by the usb-storage driver, but can
not be accessed. I compiled verbose USB in the kernel, these are the
messages on loading the usb-storage driver (the device is connected
at this point):

There are no "real" SCSI devices present.
Kernel is 2.4.16 stock, rml's preemption and lock-break patch, IDE patches
from linuxide.org. config availiable if needed.
I'd be happy to test patches if the developers do not have access to
a USBdisk device.
Thanks for your time.
