>Description:
The Apacer Handy Steno USB Flash Drive is identified as:

umass0: <vendor 0x1005 USB FLASH DRIVE, class 0/0, rev 2.00/0.50, addr 2> on uhub3
(probe0:umass-sim0:0:0:0): Uninitialized Transport 5:8000?
da0 at umass-sim0 bus 0 target 0 lun 0
da0: < USB FLASH DRIVE 1.01> Removable Direct Access SCSI-0 device
da0: 40.000MB/s transfers
da0: 124MB (253952 512 byte sectors: 64H 32S/T 124C)

The device works properly, but every few seconds the following
message appears:

umass0: Phase Error, residue = 0
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
