 Here is the output of "usbconfig dump_device_desc" relevant to the device:

 It still doesn't work out of the box on any version of FreeBSD, but I am 
 running CURRENT now, so the following makes it work:
 
 usbconfig -d 3.2 add_quirk UQ_MSC_NO_INQUIRY
 usbconfig -d 3.2 add_quirk UQ_MSC_NO_SYNC_CACHE
 usbconfig -d 3.2 reset
 usbconfig -d 3.2 reset
