Hi, I've recently bought Acer Travelmate 8371 with subj installed. I didn't find any driver for it so I can try to make one. I'm new to this whole fingerprinting thing so I don't where to write but this mailing list seems the right place.
I've dumped a small portion of USB traffic using UsbSnoop under Windows
(attached) and the protocol is exactly the same as USB mass storage
bulk-only protocol. Are there any other fingerprint devices which use
this protocol too? Maybe you have some advices?
