FWIW, that's for runtime power management. Even a wall-powered system |
| 10 |
that's always running can shutdown unused USB devices when they're not |
| 11 |
needed, saving power at the incremental level, anyway. |
| 12 |
|
| 13 |
However, that is a rather newer feature, and may cause issues with USB |
| 14 |
wakeup on obscure or older (say USB-1.x generation) hardware, thus the |
| 15 |
kernel help recommendation for that option. |

That said, presumably udisks would choose not to make its check fatal, |
| 18 |
altho changing the default to fatal could complicate things for existing |
| 19 |
ebuilds until they're fixed. |
