--------------------------------

commit a6555cb1cb69db479d0760e392c175ba32426842 upstream.

JieLi tends to use SCSI via USB Mass Storage to implement their own
proprietary commands instead of implementing another USB interface.
Enumerating it as a generic mass storage device will lead to a Hardware
Error sense key get reported.

Ignore this bogus device to prevent appearing a unusable sdX device
file.
