I am sort of a novice but am decently familiar with linux, but this one is giving me a headache. My thinkpad has an integrated UPEK fingerprint reader. Looking at it, it appears that is like disconnecting and reconnecting repeatedly. While I would like it to work, I'd be fine with just making it stop doing whatever it is doing.

From lsusb

Bus 001 Device 100: ID 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor

Bus 001 Device 116: ID 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor

every time I check lsusb its either not shown or has a different device number

dmesg is more distressing to my calm.

dmesg is pretty much nothing but this thing

I would really love any help on either making it work or disabling it so it isn't taking a dump all over dmesg

  • I have also tried echo '1-1.3' | sudo tee /sys/bus/usb/drivers/usb/unbind and it doesn't stay unbound – GORILLA.BAS Oct 4 '18 at 4:44

Perhaps this article or a similar google search would help with your situation:

How do you edit the Blacklist.conf file?

  • I think blacklisting the ehci_hcd would kill all the usb devices though – GORILLA.BAS Oct 4 '18 at 4:19
