This device is an ordinary USB flash disk made by X-Micro.
Device identification:
# camcontrol inquiry da0
pass0: <X-Micro Flash Disk 1.13> Removable Direct Access SCSI-0 device
pass0: Serial Number
pass0: 40.000MB/s transfers
# usbdevs -v (only relevant lines are shown)
Controller /dev/usb1:
addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), nVidia(0x0000), rev 1.00
port 2 addr 2: high speed, power 200 mA, config 1, Flash Disk(0x1600), X-Micro(0x0d7d), rev 1.00
>Description:
With a stock kernel, the device doesn't work after plugging it in.

The problem seems to be that the device doesn't like the
SYNCHRONIZE CACHE command which therefore must not be
issued.
>How-To-Repeat:
Just plug in the device.
>Fix:
Here is my patch which corrects the problem.
