>Description:
Quirk for United MP 5512 Portable MP3 Player (2-in-1 USB DISK/MP3).
The device is well detected...
umass0: vendor 0x8341 product 0x0000, rev 1.10/1.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Generic MUSIC DISK 0.00> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 256MB (131072 2048 byte sectors: 64H 32S/T 64C)
...but fails to function properly. It cannot be mounted (da0 is non-existent)
and any camcontrol command performed on da0 simply hangs.
After waiting for some time (or unplugging violently the device)...
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
[...]
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
[...]
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: at uhub0 port 1 (addr 2) disconnected
(da0:umass-sim0:0:0:0): lost device
umass0: detached
(da0:umass-sim0:0:0:0): removing device entry
Opened disk da0 -> 5
The "Synchronize cache failed" is quite a hint so adding a "DA_Q_NO_SYNC_CACHE"
in sys/cam/scsi/scsi_da.c eliminates the problem.
After adding the quirk the device can be mounted (da0 exists) and it functions
as expected.
For the record:
# camcontrol inquiry da0
pass0: <Generic MUSIC DISK 0.00> Removable Direct Access SCSI-0 device
pass0: 1.000MB/s transfers
# usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 1.00
port 1 addr 2: full speed, power 100 mA, config 1, product 0x0000(0x0000), vendor 0x8341(0x8341), rev 1.00
port 2 powered
