--- Comment #14 from Oliver Neukum
Unfortunately, it will take a little while until I can test this on the machine itself, BUT: I'm pretty sure /sys/bus/usb/devices/$DEVICE/power/level does not exist as you can see from the output of
for i in /sys/bus/usb/devices/1-6:1.0/power/* ; do echo -n "$i: " ; cat $i ; done
I posted above, i.e. the only files residing there are:
async, runtime_active_kids, runtime_enabled, runtime_status, and runtime_usage.
You are looking into the wrong directory. Possibly you are looking at the device, not at the interface.
That said, I could of course try the two echo commands. OTOH, I just read here https://www.kernel.org/doc/Documentation/usb/power-management.txt that power/level is deprecated since kernel 2.6.35, so I should probably try this with power/control?
It doesn't matter which file you use. Please test. -- You are receiving this mail because: You are on the CC list for the bug.
