Issue detecting with USB 3.0 device on USB 2.0 port

[Hans Petter Selasky]

Hi,

Your devices crashes or detach after receiving this 6-byte SCSI command:

12 01 00 00 FF 00 00 00 00  10 00 00 00 00 00 00

Which is an INQUIRY command.

#define SC_INQUIRY                      0x12

mav @ CC'ed.

I see there is a dirty byte there. Does the attached patch make any 
difference to you?
