not possible to enroll finger (Exception: Point is not on the curve) #24

Open rootsh0pf opened 3 years ago

rootsh0pf commented 3 years ago

I'm running dualboot Windows and Ubuntu 20.10 on a Lenovo Thinkpad Yoga 370 which has a 138a:0097 fingerprint reader. I installed libfprint-2-tod-vfs0090 from your PPA and validity-sensors-tools from snap. I enrolled my finger in Windows and tried to enroll it also in Ubuntu but it does not work: sudo validity-sensors-tools -t enroll Found device <DEVICE ID 138a:0097 on Bus 001 Address 005> Opening device 0x97 Traceback (most recent call last): File "/snap/validity-sensors-tools/65/vfs-tools/validity-sensors-tools.py", line 379, in <module> vfs_tools.open_device(init=True) File "/snap/validity-sensors-tools/65/vfs-tools/validity-sensors-tools.py", line 127, in open_device vfs_tls.parseTlsFlash(read_flash(1, 0, 0x1000)) File "/snap/validity-sensors-tools/65/vfs-tools/proto9x/tls.py", line 414, in parseTlsFlash self.handle_priv(body) File "/snap/validity-sensors-tools/65/vfs-tools/proto9x/tls.py", line 512, in handle_priv raise Exception('Point is not on the curve') Exception: Point is not on the curve fprintd-enroll also fails with no devices available

Does someone know, what the exception "Point is not on the curve" means?
