I investigated a little bit more and I think that the Goodix-TS driver that I first suspected has probably nothing to do with it. So since on this specific tablet the touchscreen the touchpad and both accelerometers are using the i2c bus, 99% this is what is happening with the stylus stuff as well, which for some reason are not recognized. Since the touchpad of this tablet is the infamous SYNA3602:00, which is handled using some explicit quirks on the i2c-hid module, I think this is what it happening with these input devices as well. Quoting Julian Sax: * This device does not supply any descriptors and on windows a filter * driver operates between the i2c-hid layer and the device and injects * these descriptors when the device is prompted. The descriptors were * extracted by listening to the i2c-hid traffic that occurs between the * windows filter driver and the windows i2c-hid driver. I have a feeling that this process should be repeated for the rest input devices. I have the same problem but with other configuration:

Sorry... comment on wrong bug report. Please ignore. Good news, I've written a patch to properly report the stylus/pen events as stylus events and submitted this upstream, see: https://lore.kernel.org/linux-input/20211207100754.31155-1-hdegoede@redhat.com/T/#t |
