0671c066 | 2437 | * 2. They will not wakeup when autosuspended and receiving data |
aa17e8ce IFM |
2438 | * on their bulk RX endpoint from e.g. a keyboard or mouse |
2439 | * (IOW remote-wakeup support is broken for the bulk endpoint). | |
0671c066 HG |
2440 | * |
2441 | * To fix 1. enable runtime-suspend, force-suspend the | |
f4292e2f | 2442 | * HCI and then wake-it up by disabling runtime-suspend. |
0671c066 | 2443 | * |
