Subject: [BUG] bcm5974: Mouse disappears after suspend/resume
Hello,
for some kernel versions (probably starting around 3.5) I see that
after some amount of suspend & resume cycles, the mouse is not
visible anymore. partly [0] and full dmesg output attached.
Hardware is the MacBook Air 4.2.
Last tested kernel is 3.7.9-1-ARCH. Now the interesting bits:
Unloading and reloading the module SEVERAL times, makes it work again:
[15:48] brief:~# while true; do rmmod bcm5974; sleep 0.3; modprobe bcm5974; sleep 0.5; done
I need to let the loop run until I see
[101637.155073] usbcore: registered new interface driver bcm5974
in dmesg. Afterwards I reset the mouse sensitivity using
xinput --set-prop bcm5974 "Trackpad Sensitivity" 0.3
Does anyone spot the source of the problem / is anyone aware of a working
version?
Cheers,
Nico
