Re: USB autosuspend causing trouble with bluetooth

[Kirill Elagin]

Things just got way worse with this hotplug thing.
When the host power/control is set to `auto`, as soon as I insert  the
Unifying receiver one of kworkers starts eating 100% of one of the
cores, according to `htop`. As soon as I `echo on` to power/control of
the relevant USB hub the kworker stops doing this. This also happens
with that other USB1.1 BT-dongle, so I assume any USB1.1 device would
do. Also just unplugging the device is not enough, the kworker keeps
eating CPU until I `echo on` to power/control.

Should I start a separate thread?
Right now I'm on 3.18.2-gentoo.
