>Description:
When attaching device kernel reports this:
Aug 21 22:46:15 limbo root: Unknown USB device: vendor 0x058f product 0x6387 bus uhub3
Aug 21 22:46:15 limbo kernel: umass1: <JetFlash Mass Storage Device, class 0/0, rev 2.00/1.00, addr 3> on usbus3
Aug 21 22:46:15 limbo kernel: umass1: SCSI over Bulk-Only; quirks = 0x0100
Aug 21 22:46:16 limbo kernel: umass1:2:1:-1: Attached to scbus2
Aug 21 22:46:16 limbo kernel: (probe0:umass-sim1:1:0:0): TEST UNIT READY. CDB: 0 0 0 0 0 0
Aug 21 22:46:16 limbo kernel: (probe0:umass-sim1:1:0:0): CAM status: SCSI Status Error
Aug 21 22:46:16 limbo kernel: (probe0:umass-sim1:1:0:0): SCSI status: Check Condition
Aug 21 22:46:16 limbo kernel: (probe0:umass-sim1:1:0:0): SCSI sense: UNIT ATTENTION asc:28,0 (Not ready to ready change, medium may have changed)
Aug 21 22:46:16 limbo kernel: da4 at umass-sim1 bus 1 scbus2 target 0 lun 0
Aug 21 22:46:16 limbo kernel: da4: <JetFlash TS4GJFV85 8.07> Removable Direct Access SCSI-2 device
Aug 21 22:46:16 limbo kernel: da4: 40.000MB/s transfers
Aug 21 22:46:16 limbo kernel: da4: 3900MB (7987200 512 byte sectors: 255H 63S/T 497C)
Aug 21 22:46:24 limbo kernel: (da4:umass-sim1:1:0:0): SYNCHRONIZE CACHE(10). CDB: 35 0 0 0 0 0 0 0 0 0
Aug 21 22:46:24 limbo kernel: (da4:umass-sim1:1:0:0): CAM status: SCSI Status Error
Aug 21 22:46:24 limbo kernel: (da4:umass-sim1:1:0:0): SCSI status: Check Condition
Aug 21 22:46:24 limbo kernel: (da4:umass-sim1:1:0:0): SCSI sense: ILLEGAL REQUEST asc:26,0 (Invalid field in parameter list)
After that any time SYNCHRONIZE CACHE command is issued writing to device stops for some time and kernel reports bad command.
>How-To-Repeat:
Attaching the device and trying to work with it should suffice.
>Fix:
Apply the following patch.
