Query and control PowerUSB power strips

NOTE: a number of features are TBD

Identifying strips and sockets

Each strip is identified by the USB bus and device numbers. A strip ID is the bus number and device number separated by a colon:

  • 0:1 - The power strip on bus 0, device 1

Each strip has 3 controllable sockets, numbered 1-3. A socket is identified by the strip ID followed by a colon and the socket number.

  • 0:1:2 - Socket 2 on power strip 0:1

Get the list of connected strips and status

powerusb [--list-strips]
