Greg, bad guessing. This is not the device's fault but the linux usb
drivers are buggy.

The messages:
bInterfaceClass cannot get string descriptor 1, error = Broken
pipe(32)
cannot get string descriptor 2, error = Broken pipe(32)

go away after "rmmod hid" (or whatever driver is using the device).

This is a long standing bug.
