This device is a USB CD-RW, not recognised as such by any FreeBSD 
versions since the first time I tried on 4.7.
I first reported in 5.3, though.
With some work, I managed to use it as Read Only umass device. :)
http://lists.freebsd.org/mailman/htdig/freebsd-usb/2005-February/000660.html
Pretty useless as the mission was to backup data.
At that point I had some USB flash memories available and no time for 
playing with this device any more.
As a matter of fact, it's been in a drawer for more than 2 years.
The main problem seems to be related to the CSWTag returned by this 
device, most probably a broken firmware issue.

Please, feel free to drop this PR if the contents are not relevant to 
anybody else but me. I am not for trying to fix every broken firmware in 
the hood by patching kernel.
