User:Hugh Jorgan/USB device power consumption

Continious Tx / Rx / TxRx modes are not quite continious. I will simply be running iperf (stock settings aside from test length) C -> S (Tx), S -> C (Rx), and simultaneously+bidirectionally (TxRx).

General notes:
 * measurements are non-automated (currently)
 * accuracy is questionable
 * some estimates are made
 * the 'nets' stat is useless
