A standalone win64 program which attempts to imitate winbio framework by dynamically loading the synaWudfBioUsb.dll driver and making ioctl requests to scan/enroll fingers.

To build you will need a 64bit version of mingw cross-compiler and winbio_ioctl.h/winbio_types.h from wdk/visual studio/whatever. Use mk script to rebuild the a.exe. Collecting all the required header files is a tedious process, so this project contains a pre-compiled version of a.exe.

To run:

• Clone and build Wine with hacks designed specifically for this thing to work. Can be built in Docker, for example

$ git clone https://github.com/uunicorn/wine -b hacking/validiy-sensor && cd wine
$ docker build -t wine:validity .

• Download the Windows driver and extract contents with innoextract
• Copy synaWudfBioUsb.dll from the extracted windows driver to the current directory
• Copy *.xpfwext file from the extracted windows driver to the current directory
• Create a file usb.txt with your USB device id:

$ echo '138a:0097' > usb.txt`

• Determine your fingerprint USB bus and device path:

DEVICE=$(lsusb -d 138a: | awk -F '[^0-9]+' '{ print "/dev/bus/usb/" $2 "/" $3 }')

• Run a.exe inside the container with one of the following options:

$ ./run.sh [ nop | identify | enroll ] 

• It may "fail" the first couple of times. Whenever driver detects that device ownership has changed (host computer details have changed), it needs to re-flash and re-calibrate the device to establish a new trust. After each step the USB device is reconnected. The current winusb stub is not smart enough to detect device reconnects, so the next driver's attempt to talk to the device will immediately fail. Just restart a.exe a couple of times before giving up.
