``int ioctl(int fd, FE_DISEQC_RESET_OVERLOAD, NULL)``
Arguments
=========

If the bus has been automatically powered off due to power overload,
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.
