Comments on: udev, the “authorized” attribute and other failed attempts to ban a bogus USB keyboard https://billauer.se/blog/2023/04/usb-webcam-keyboard-ban/ Anything I found worthy to write down.

Your article helped me notice that 72-... is the right spot to put a TAG-="uaccess" rule.

I ran this whole thing on a very old distribution. And I did this almost a year ago. So next time, if there will be any, I'll try your suggestion. Thanks. You seem to have a point there.

It made my mouse ignored in X LIBINPUT_IGNORE_DEVICE is probably not used in libinput-device-group (looking at my 80-libinput-device-groups.rules)
Maybe add
ENV{LIBINPUT_IGNORE_DEVICE}==”1″, GOTO=”libinput_device_group_end”
before the call. It made my mouse ignored in X

But that didn't work either, not clear why. That’s exactly what I tried with 79-no-camera-keyboard.rules, which is shown later on in the post. But that didn’t work either, not clear why.

I did not 100% follow through the LIBINPUT_IGNORE_DEVICE fail however. Would you not be able to create a rule that triggers earlier than 80-libinput-device-groups.rules and filter by vendor/product ID if the name was not available? Hi,
