wacom driver failing to probe CTC4110WL

[dimitris-personal]

hid-generic was binding the BT device but I was facing issues (appearing twice on libinput list devices and others) so I disconnected, cycled bluetooth, loaded wacom module (wasn't loaded before) and tried to bind it:

$ echo "0005 0531 0101" | sudo tee /sys/bus/hid/drivers/wacom/new_id
Place your right index finger on the fingerprint reader
0005 0531 0101

Then I turned on the tablet again and:

May 03 20:34:11 kernel: wacom 0005:0531:0101.001D: probe with driver wacom failed with error -22

and tablet no longer detected.

Am I reading the wiki right that the device is supported?

Kernel is 6.19.14-300.fc44.x86_64 on Fedora 44 Workstation.

This device should go with hid-generic driver since its vendor ID is 0531, instead of 056a. Can you share the output related to hid-generic?

Without any overrides, and now on kernel 7.0.9 FWIW, with bluetooth (no wired connection to the host):

The underlying issue I was trying to fix with force-binding to the wacom driver is that the tablet appears twice in the desktop settings:

Not sure where in the stack the issue first arises (are the two input kernel lines above related?) but I assume this isn't the repo to track this?

The wacom.ko only processes the devices that use the Vendor ID of 0x056A. That's why you get the "driver wacom failed with error -22". When your Wacom One was driven by hid-generic driver, can you move the cursor by your pen? If yes, your device is good. The duplicated "Wacom One" entries in Gnome settings is most likely a Gnome issue. I remember seeing that with other devices too.
