Check that you don't have usb power saving enabled for all devices when |
| 23 |
on battery. |

I've run into this before and it's enough to drive one nuts :-) My |
| 26 |
previous laptop was especially bad - super keen to shut down the usb |
| 27 |
port after 30 seconds of inactivity and very very loathe to getting |
| 28 |
around to waking it up again. |

Powerdevil has gone through some changes over the past period, there |
| 31 |
might be a new default in place that you aren't aware of yet. |

powertop is a very useful tool for info about what power saving features |
| 34 |
are active. |
