Hello, I have recently installed 9front on my laptop and only some USB mice seems to work. After a bit of investigation it turned out to be a problem with the devices which also presented part of them as a keyboard, so I looked a bit at the USB hid spec. It seems that some things that nusb/kb does (like setting the idle time) is not always supported by all devices, so this patch changes those things. It fixes the problem for me and now I can use my new mouse :) Sysinfo is attached.
