Hi! No code yet, just a kind request for comments and hopefully some wisdom and experience from Nikolai dealing with HUION devices. HUION keeps reusing the same vendor and product IDs for their devices. This makes it really difficult to differentiate between devices and handle them in the kernel and also in user space. Reusing IDs could introduce a problem: If HUION, or other vendor following the same practices, releases a new tablet with a duplicated product ID, the UCLogic driver would handle it. The device might work with the existing code or it might fail because of a new feature or a whole different firmware. As far as I know, at the moment there is not a mechanism in place to avoid this situation. I think that it'd be better to ignore those devices in UCLogic and let the HID generic driver handle them because using HID generic would provide a basic user experience while using UCLogic might fail to probe the tablet. DIGImend's web already provides a nice list of supported devices: http://digimend.github.io/tablets/ So, I wonder: - Do you think it makes sense to ignore untested devices? - If the answer is yes, do we have a better option than checking the device name against an allow-list? It'd be great to hear other people's ideas. Best wishes, José Expósito
