    This "device" was one autogenerated by syzbot. There are a lot of issues in

    size.

    This leads to report->size being set to 0 and can mess up with usbhid
    internals.  Fortunately, uhid merely passes the incoming buffer, without
    touching it so a buffer of size 0 will be translated to [] without
    triggering a kernel oops.

    Because the report descriptor is wrong, no input are created, and we need
