>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: ugen0.3: <PB> at usbus0

device
Jan 17 19:27:05 admin kernel: da0: 40.000MB/s transfers
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.
