Logitech G700s extra G buttons don't work in wireless mode

[Lastique]

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 problem appeared after upgrading Kubuntu 19.10 to 20.04. It was not present on 19.10.

The workaround is to blacklist hid_logitech_hidpp and hid_logitech_dj modules by adding /etc/modprobe.d/blacklist-hid_logitech.conf with this content:

```
blacklist hid_logitech_hidpp
blacklist hid_logitech_dj
```

and running `update-initramfs -u -k all`. After reboot, the buttons start working as expected.

[Andrzej (jarzebowski-andrzej)]

I got the same issue after updating from 18.04 to 20.10 (I did following update in one go 18.04 > 20.04 > 20.10, kernel x86_64 Linux 5.8.0-28-generic).

I had issue with Logitech G604 using dongle. Buttons G4 and G7 (two buttons on the side, closest to the back of the mouse) stopped working plus when dongle was reconnected while system was running, scroll up and down was not working after the re-connection.

The workaround for scroll issue was either to reboot whole machine or switch mouse into Bluetooth mode and back to dongle mode.

Thankfully workaround by user Lastique works, both issues disappeared.
