The error you're seeing is a bit different from me.
Can you reply with the output of 'lsusb -v'?
I have a suspicion that Linux is fine and that the USB descriptor for
the device is bad. My device has an Endpoint descriptor with
bDescriptorType 0x25, which seems to be an invalid value (should be 0x5).
