I ran into the same thing with my LaCie USB-based SCSI drive, and in that
case, it wan't a USB problem at all, it was a SCSI problem.
In *that* case, the solution was to go to
/usr/src/sys/cam/scsi,
and edit scsi_da.c
(This is the SCSI "Quirks" file)
and add an entry for my drive telling the kernel not to use 6-byte mode with
my drive. Then I built and installed a new kernel and voila! it worked.
If you have an up-to-date kernel, the code for my drive lives (as of
yesterday, anyway) at line 265:
{
/*
* LaCie USB drive, among others
*/
{T_DIRECT, SIP_MEDIA_FIXED, "Maxtor*", "D080H4*", "*"},
/*quirks*/ DA_Q_NO_6_BYTE
},
In your case, it would be a little trickier; my disk is recognzied as
Mar 13 02:51:24 i8k /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Mar 13 02:51:24 i8k /kernel: da0: <Maxtor 4 D080H4 DAH0> Fixed Direct Access
SCSI-0 device
which is where I got the above strings.
Your disk seems to have no name (?) based on the leading space:
| da0: < USB DISK 1.05> Removable Direct Access SCSI-0 device
so you might have to find somebody more expert than me, but for your own
tests you could just enable this "quirk" for "*", "*", "*", and that would
prresumably ensure that nobody used 6-byte for anything. Then you could look
around to find a more subtle string that could be committed back to the man
source track so that you won't have to re-patch the file every time you
upgrade.
