I had that story long time ago. I've got A-DATA MyFlash FP1 stick with fingerprint unlock. Somehow it didn't work on Linux. I sniffed the USB and figured out that after fingerprint check it simply sends a fixed 3-byte command to the stick to switch to real storage instead of dummy storage. You don't even need the password to unlock it.
