Linux 3.2 and Logitech Unifying Receiver

I just upgraded to gentoo-sources-3.2.9 from 3.1.1 only to find out that my logitech wireless mouse stopped working. It was correctly detected as a usb device but no input device was created for it:

Bus 005 Device 004: ID 046d:c52b Logitech, Inc. Unifying Receiver

After some Googling and looking around kernel settings I found out that I had to enable Device Drivers -> HID Devices -> Special HID drivers -> Logitech devices -> Logitech Unifying receivers full support. Hopefully this information helps other Gentoo users who run with most things disabled. Updating the kernel with make oldconfig I did not notice this option because I have had CONFIG_HID_LOGITECH disabled and it hasn’t caused any problems.

  1. You might want to all make sure people know they’ll need to add HID Raw too

    I fell fowl of that too

  2. This is because you have CONFIG_EXPERT (aka. CONFIG_SHOOT_SELF_IN_FOOT) enabled. There you need to be extra careful on kernel upgrades.

  3. Strange is that I have the Unifying Receiver working for my keyboard and M180 mouse without any problem, but I’ve also bought a Performance MX mouse and I have to pull out and then in the usb connector to activate it…
