Hi Clement, I have a series I sent last September that allows to support non DJ devices on logitech-hidpp (https://patchwork.kernel.org/project/linux-input/list/?series=16359). In its current form, with the latest upstream kernel, the series will oops during the .event() callback, which is easy enough to fix. However, I am currently trying to make it better as a second or third reading made me realized that there was a bunch of non-sense in it and a proper support would require slightly more work for the non unifying receiver case. I hope I'll be able to send out something by the end of the week. Cheers, Benjamin
