>Description:
The TrekStor MusicStick is a USB MP3 player with a umass interface using
the bulk-only transfer method. The UBS driver identifies it as:

Dec 24 12:51:57 pussyfoot /netbsd: umass0: TrekStor, Inc. TrekStor MusicStick, r
ev 1.10/0.01, addr 2
Dec 24 12:51:57 pussyfoot /netbsd: umass0: using SCSI over Bulk-Only

When the device receives a command that it does not understand it
seems to fail on all subsequent data transfers showing:

Dec 24 12:52:29 pussyfoot /netbsd: umass0: BBB reset failed, IOERROR
Dec 24 12:52:29 pussyfoot /netbsd: umass0: BBB bulk-in clear stall failed, IOERR
OR
Dec 24 12:52:29 pussyfoot /netbsd: umass0: BBB bulk-out clear stall failed, IOER
ROR
Dec 24 12:52:29 pussyfoot /netbsd: sd0(umass0:0:1:0): generic HBA error

>How-To-Repeat:
Plug in a TrekStor and try to access it, e.g with 'disklabel sd0'.

>Fix:
I have added NODOORLOCK and NOSYNCCACHE quirks to avoid the corresponding
commands.

It is possible that some other fixes from -current in the scsipi
layer are required as well.
