SYNOPSIS

     usbconfig [-u unit] [-a addr] [cmds...]
     usbconfig [-d [ugen]<unit>.<addr>] [cmds...]

DESCRIPTION

     The usbconfig utility is used to configure and dump information about the USB subsystem.

     The options are as follows:

     -u unit   Limit device range to USB devices connected to the given USBUS unit.

     -a addr   Limit device range to the given USB device index.  Should only be used in conjunction with the unit argument.

     -d [ugen]<unit>.<addr>
	       Limit device range to USB devices connected to the given unit and address.  The unit and address coordinates may be prefixed by the
	       lowercased word "ugen".

     -h        Show help and available commands.

     When called without options, usbconfig prints a list of all available USB devices.
