Public bug reported:
I have a wired trackball which identifies itself through lsusb as...
Bus 003 Device 013: ID 047d:1022 Kensington Orbit Optical
This device is perfectly functional when my Dell Q15R (N5110) is powered
from the mains, but when running on battery, the device lasts something
like 10 seconds before being disabled.
Unplugging and replugging the trackball gets you another 10 seconds.
Keeping moving the pointer can sustain the function of the trackball,
until you leave the pointer still for 10 seconds, and then it's
disabled.
Plugging the mains back in and replugging the trackball means the
trackball keeps functioning indefinitely.
I don't know what kind of power module unload is built in to 12.04. Is
it possible that something is being unloaded which shouldn't be? Any
suggestions for workarounds? I'd really like to be able to use my
trackball when running on battery.
