I have a fingerprint reader on my laptop that works under windows that doesn't show up on lsusb
. Which means its not connected via USB. Through some digging around, I found out that this specific device connects via SPI. I've seen some tutorials on the internet about reverse engineering windows USB drivers for linux but not for something like this.
My device is an ELAN 04f3:3104
embedded fingerprint reader that works with the windows WBF fingerprint reader driver. Any pointers much appreciated!
