In the debianforum.de i got the hint, it's a kernel-problem, so i'm
mailing this to the list.
Hope you can help me, and you got enough information.
First, what version of the kernel are you using?
Next, please post the output from "lsusb -v" for this device. Also,
post the contents of /sys/kernel/debug/usb/devices.
