I ask you to add a new quirk for a noname USB flash drive. It freezes
randomly with complains like "Synchronize cache failed"
# camcontrol inquiry da0
pass0: < USB BAR 1.89> Removable Direct Access SCSI-2 device
pass0: Serial Number
pass0: 1.000MB/s transfers
There is no such quirk in DA_OLD_QUIRKS
Here is the patch which seems to make it work
