RPi Bugs

See R-Pi_Troubleshooting for problems that are not bugs.

= Hardware =
 * 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.
