The USB drive in question appears to go tits up when we send it an
extended inquiry.  I contemplated adding a BLIST option but we really
only need EVPD to access pages 0xB0 and 0xB1.  The Block Limits page
appeared in SBC2 so I'm just trying to play it safe.  And hopefully fix
Tarkan's problem in the process.
