BAD BAD BAD You've found a piece of hardware that is broken. Please report the `lsusb -v` output and tell us which devices are affected. This way Sarah can maybe check and fix this upstream. for now, I advise you to not use the usb suspend suggestions in powertop :) > Is this the desired effect of enabling USB auto-suspend? obviously not :) > Or was the previous behavior the correct one? Hhmm, shouldn't it be something > in between, i.e, that USB get suspended when I'm not using the keyboard or > mouse but that it wakes up when I do? usb suspend was largely broken in older kernels. newer kernels honor the powertop changes but thus expose broken devices.
