Don't think so, as there is no windows for BE hardware....maybe some windows 
ce platforms? but then: there is only Windows and Mac drivers for the us122, 
or?
Well, the right thing to do in the first place is to let jack work with LE 
Audio on a BE platform. Will look into that.

You'd use an usbsnooper for for Mac. If that already exists. You might also 
contact the "usb midi firmware" project on Sourcefourge.
They know how to extract the firmware from the windows driver files.
