Created attachment 288765 [details] Output of `libinput list-devices` when the mouse is wired Starting with Linux kernel 5.4.0, extra buttons G4-G10 on the side and top of the Logitech G700s mouse don't work when the mouse is connected over the wireless dongle. The buttons do work in wired connection. The problem is not present with kernel 5.3.18. It is present with 5.4.28, 5.5.19, 5.6.7. In wireless mode, the `libinput list-devices` command does not show additional input devices, including the keyboard device, associated with the mouse. Only the "Logitech G700s" pointer device is shown.

This may be related to https://bugzilla.kernel.org/show_bug.cgi?id=204519 , although that bug describes the opposite problem (the buttons didn't work in wired mode).
The workaround is to blacklist hid_logitech_hidpp and hid_logitech_dj modules. After that the buttons start working as expected.
When I hook the receiver, I get https://pastebin.com/hUSZA63G: ``` [396619.063389] logitech-djreceiver 0003:046D:C531.003E: logi_dj_hidpp_event: invalid device index:254 ``` I was looking at recent changes, and I'm guessing this commit is to blame: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=992ff2cc9ec6e30ccc64c341b052e8ccb370db90
