| 30 | Description |
| 31 | =========== |
| 32 | |
| 33 | If the bus has been automatically powered off due to power overload, |
| 34 | this ioctl call restores the power to the bus. The call requires |
| 35 | read/write access to the device. This call has no effect if the device |
| 36 | is manually powered off. Not all DVB adapters support this ioctl. |
| 37 | |
| 38 | RETURN VALUE |
| 39 | |
| 40 | On success 0 is returned, on error -1 and the ``errno`` variable is set |
| 41 | appropriately. The generic error codes are described at the |
| 42 | :ref:`Generic Error Codes <gen-errors>` chapter. |
