Hello, As far as I could see, there is no mapping to BTN_STYLUS2 (a second button on the pen barrel, AFAIK) in hidinput_configure_usage, however some specific drivers use it. Is it because there is really no usage code for it in the HID Usage Tables document? If so, maybe there is some widely used usage code for such button, which we could use? So far I've seen "Eraser", "Tablet Pick" and, possibly, "Invert" used in UC-Logic, Kye and Waltop tablets respectively. To me, "Tablet Pick" looks the least of evils. I'm asking because many tablets have these buttons and having all of them using input_mapping just for this would be too much, IMHO. I'm looking forward to adding support for several, at least, and attempting to do so by only providing fixed report descriptors, if possible. Thank you.
