this ioctl call restores the power to the bus. The call requires |
|
read/write access to the device. This call has no effect if the device |
|
is manually powered off. Not all Digital TV adapters support this ioctl. |

On error -1 is returned, and the ``errno`` variable is set |
|
appropriately. |
