>Description:
 When connecting PocketBook 912 Pro to USB port, system shows the following output:

Jan 17 19:24:52 admin kernel: ugen0.3: <PB> at usbus0
Jan 17 19:24:52 admin kernel: umass0: <PB PocketBook, class 0/0, rev 2.00/3.24, addr 3> on usbus0
Jan 17 19:24:52 admin kernel: umass0:  SCSI over Bulk-Only; quirks = 0x0100
Jan 17 19:24:52 admin kernel: umass0:5:0:-1: Attached to scbus5

        It seems like system can't recognize it as mass storage device. As result, mount is impossible.

usbconfig dump_device_desc

ugen0.3: <PocketBook PB> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0040
  idVendor = 0x0525
  idProduct = 0xa4a5
  bcdDevice = 0x0324
  iManufacturer = 0x0001  <retrieving string failed>
  iProduct = 0x0002  <retrieving string failed>
  iSerialNumber = 0x0003  <retrieving string failed>
  bNumConfigurations = 0x0001

>How-To-Repeat:
just connect PocketBook 912 Pro to USB port
>Fix:
1 Remove device from port;

2 run the following command as root: usbconfig add_quirk UQ_MSC_NO_SYNC_CACHE;

3 attach device.

 System messages after command above and device attach:

Jan 17 19:27:05 admin kernel: da0: 954MB (1955232 512 byte sectors: 64H 32S/T 954C)

For now it can be mounted as DOS fs.
