  45     <para>If the bus has been automatically powered off due to power overload, this ioctl
  46  call restores the power to the bus. The call requires read/write access to the
  47  device. This call has no effect if the device is manually powered off. Not all
  48  DVB adapters support this ioctl.</para>
