================================================================
Actually it might be interesting just to try those two flags on *any*
usb-connected DA device, since they seem to be needed for most solid-state
devices and many real disks. That would cut back a bunch on the quirk
table, and especially on the need to figure out a device-id and recompile the
kernel each time you try something new... (or arbitrarily set the appropriate
flag on any device when a 6-byte read or a sync_cache gives a command error,
then retry). It isn't clear from /var/log/messages just what error is
reported for this case; full sense isn't in the "read" log message, only
a timeout.
(sync-cache is clearer...)
The device works fine with my suggested diff (except that it single-threads
rather badly, but one can live with that). Cool having a 128mb USB "disk"
that isn't much bigger than the plug.
