I browsed their udev rules and found some rules pointing in that |
23 |
direction but none specifically matching the PCI ID of my keyboard and |
24 |
the wildcards ... I am not sure. |
25 |
|
26 |
But they seem to do it specifically, yes -> |
27 |
|
28 |
# cat /sys/module/usbcore/parameters/autosuspend |
29 |
2 |
30 |
|
31 |
# my keyboard |
32 |
# cat /sys/bus/usb/devices/3-1.6/power/control |
33 |
on |
34 |
|
35 |
I assume it won't hurt much if I disable USB autosuspend in general for |
36 |
now? Power savings should be minimal, right? (desktop here, AC etc) |
