29 | =========== |
| 30 | ||
| 31 | If the bus has been automatically powered off due to power overload, | |
| 32 | this ioctl call restores the power to the bus. The call requires | |
| 33 | read/write access to the device. This call has no effect if the device | |
| 34 | is manually powered off. Not all DVB adapters support this ioctl. | |
