  • The current R-Pi firmware limits users to 2 hubs and 14 ports.
  • Some Hardware is unsupported. link
  • The analog sound output chip suffers from a clicking problem when it awakes from sleep.
This is caused by the quiet signal sitting at half rail when the chip is active and the signal
sitting at ground when the chip is asleep. During the wake/sleep process the analog output is rapidly
driven between these two levels causing an annoying, but not damaging, click.
Recent versions of software drivers have accounted for this problem by being far less aggressive in putting
the audio DAC to sleep.
