Hello, I have been provided by my company a dell vostro 3350 laptop last week, and I had to reformat the hard disk in order to install ubuntu. I lost the drivers and the windows app, thus I'm unable to snoop the usb traffic. The device is the following (relying on lsusb output) :
Bus 002 Device 003: ID 138a:0011 DigitalPersona, Inc It seems that someone here already posted some usb snooping sessions, I wrote a python snippet which tries to mimic the urb sent to the device, but I'm a bit stuck with reverse engineering for now (the device on the capture files does not seem to be "plugged" at the same place as on my laptop - hypothetically bus 3 device 4 in the provided logs, bus 2 device 3 on mine). - Is there a special windows app to install in order to be able to snoop the usb traffic ? I successfully installed the driver into a win seven virtualbox, but I could not manage to find a suitable software to use it concretely. - Is there anybody here currently working on the same device ? I tried to hack around the vfs101 driver with no luck, the initialization process does not look the same, and adding the vendorId / productId into the sources does not do the trick unfortunately. I got the following output, trying to use the enroll example: Scan your finger now. vfs101:error [async_recv_cb] seqnum mismatch, got 0401, expected 0000 async:error [fpi_drvcb_enroll_stage_completed] BUG at async.c:161 sync:error [fp_enroll_finger_img] unrecognised return code -5 Enroll failed with error -22 - Additionally, do you have some hints in order to get started with the current fprint code ?
