(Initially on https://bugs.archlinux.org/task/63686 )

A recent commit added some Logitech mouse models to hid-logitech-hidpp [1]. However, Logitech G102 Prodigy is not working well with it, sometimes showing up this on boot:

> [ 34.187560] logitech-hidpp-device 0003:046D:C084.0002: Device not connected

Thus leading to a delay on mouse in the boot. It seems that master branch has partially reverted the commit [2], while 5.2.x hasn't. I'm not sure of other mouse models, but at least Logitech G102 Prodigy (C084) has this problem and shall not be added to hid-logitech-hidpp's list for now. Therefore, could the revert [2] (or at least for model # C084) be backported on 5.2.x? Thanks.

Not an issue anymore since Arch Linux has updated to 5.3.x which includes this commit.
