Thinkpad Fingerprintreader

[myaltisgreat]

I’ve installed Manjaro yesterday (Kernel 5.10.42-1-MANJARO) on my Thinkpad E490. Everything is great, but I’m stuck with one issue: the fingerprint reader.
I’ve followed the Arch Wiki fingerprint-Tutorial and when I try to add a fingerprint, it just tells me that no device is found.

The lsusb -d 06cb:00a2 -v output for the reader is this:

How should I proceed?

In short: There is no driver for linux and i guess if lenovo will not develop one, then there will be none. The connection is encrypted and needs to be reversed-engeneered if lenovo does not help…
