Grain-media GM12U320 based devices are mini video projectors using USB for both power and video data transport. Their usb-storage interface is a virtual windows driver CD. The gm12u320 kms driver needs these interfaces to talk to the device and export it as framebuffer & kms dri device nodes, so make sure that the usb-storage driver does not bind to it.
