Mine is a "Suxess", I don't even know if it's the real brand...
It works fine after I changed the sysctl variable kern.cam.da.no_6_byte
to 1 (on older systems that variable does not exist, you have to add
"quirks" to scsi_da.c).

Here's how is seen the key:

Aug 12 09:54:09 marduk /kernel: umass0:          USB Disk    , rev 1.00/1.00, addr 2
Aug 12 09:54:09 marduk /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Aug 12 09:54:09 marduk /kernel: da0: < USB DISK 1.05> Removable Direct Access SCSI-0 device 
Aug 12 09:54:09 marduk /kernel: da0: 650KB/s transfers
Aug 12 09:54:09 marduk /kernel: da0: 15MB (32000 512 byte sectors: 64H 32S/T 15C)
