I am attempting to write a Mac driver for this device...
http://www.thinkgeek.com/gadgets/security/698d/
The USB prober output is below...
The "boot interface" seems to imply that firmware is downloaded, but
If I could observe the Device descriptors once the driver is loaded
under windows, I could get a better understanding of the operation of
this device (sans any documentation)
