Interesting. Is there any chance that the updated USB HID driver would enable Wacom touchscreen and pen support? On my ThinkPad Yoga, touching the screen or using the pen still doesn't work, but locks out all future mouse clicks, using version 2023.10.10.
We did not address USB touchscreen support in the updated HID driver, but disabled absolute motion handling for now. I do not have a Wacom device at hand but my ELAN touchscreen reports BTN_LEFT press/release on touch and logs dropped events.

For some reason, the Linux driver code seems to interpret your Wacom events differently and confuses the input handling. You may have a look at it with the event filter <log> feature.
- Copy /config/managed/event_filter to /config/
- Find line <input name="usb"/> in /config/event_filter
- Change to <log prefix="USB "><input name="usb"/></log>
- Examine /report/log for the reported input events
Thanks for the detailed instructions! Sorry for taking so long to respond to this.
I noticed Norman's mention of your efforts to add touchscreen support in the "What's new in Sculpt OS 23.10" Genodians article, and I've been testing using your depot. I have attached some relevant lines from the log, using both finger and pen.
There are quite a few dropped events, and both the pen and touch seem to confuse Nitpicker, because no further button clicks are registered until rebooting. Fortunately the keyboard continues to work, which is how I could save the log file. :^)
I would love to continue testing this as you continue. (Now that I know how to do it, I will respond faster.) I will keep an eye on your depot - please let me know how I can best help!
Thanks!
