OK, not only it didn't fix problems with logitech mouse (see below),
but removing mouses USB dongle effectively crashes kernel, so this one probably
shouldn't be applied :).

[  330.721629] logitech-djreceiver: probe of 0003:046D:C52F.0013 failed with error 7
[  331.462335] hid 0003:046D:C52F.0013: delayedwork_callback: logi_dj_recv_query_paired_devices error: 7

Kind regards,
Petr
