I did not post the correct devices in my previous comment.
The two affected devices are:
Bus 002 Device 004: ID 046a:0023 Cherry GmbH CyMotion Master Linux Keyboard G230
Bus 002 Device 003: ID 046d:c24c Logitech, Inc. G400s Optical Mouse
Mouse and keyboard, respectively. Both connected with their standard USB
cable.
This issue is about USB only (not bluetooth related).
** Description changed:
This issue is a regression after update to 16.04 (coming from 14.04). To
my knowledge, I was using TLP together with 14.04, which got removed
during the upgrade in favour of upower.
Two devices behave unexpected reproducably after a fresh reboot:
- Bus 002 Device 005: ID 413c:8187 Dell Computer Corp. DW375 Bluetooth Module
Bus 002 Device 004: ID 046a:0023 Cherry GmbH CyMotion Master Linux Keyboard
G230
+ Bus 002 Device 003: ID 046d:c24c Logitech, Inc. G400s Optical Mouse
It looks like a power management related issue. By default,
- USB mouse pointer is invisible and mouse looses any event unless I press a
mouse button (which also is executed in a dangerous manner at the last position
of the invisible pointer)
- USB keyboard is inactive unless I press a few keys. These first characters
get lost in the output
- This happens directly after reboot (e.g. first characters of password get
lost, mouse is invisible).
- After login, it still happens: After a few seconds of inactivity, mouse and
keyboard are non-responsive again.
- In addition, I also experience lost events without any delay from time to
time
- In addition, scrolling with the mouse is laggy in particular
Most of these problems are gone as soon as I disable powersave in
powertop for mouse and keyboard:
Bad Automatische Bereitschaft für USB-Gerät G400s Optical Gaming Mouse
[Logitech]
- Bad Automatische Bereitschaft für unbekanntes USB-Gerät 2-1.2 [046a:0023]
+ Bad Automatische Bereitschaft für unbekanntes USB-Gerät 2-1.2 [046a:0023]
The only remaining problem is laggy scrolling and sometimes loosing
events like keyboard presses, but this could still be another issue.
The powertop status of other USB devices does not have an effect on this
workaround. However, the workaround via powertop is lost after next
reboot.
It also has no effect when changing USB-Ports or USB-Controllers. I tried
- built-in USB 2.0 Ports of my DELL Latitude E5510 (1d6b:0002)
- replicated USB 2.0 ports of my docking station PR02X (1d6b:0002)
- PCMCIA USB 3.0 Express card (1d6b:0003)
Accordingly, this issue is not related to particular USB
controllers/hubs. Plus, as two non-related USB hardware devices are
concerned, this issue also might not be related to particular USB
devices, bat rather affect many USB devices.
I don't experience any problems when using the built-in keyboard of the
DELL Latitude E5510.
