NAME
     usbconfig — configure the USB subsystem

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.

     Show information about the device on USB bus 1 at address 2:

	   usbconfig -u 1 -a 2 dump_info

     Dump HID descriptor for device on USB bus 1 at address 2:

	   usbconfig -u 1 -a 2 do_request 0x81 0x06 0x2200 0 0x100

     Dump string descriptor at index Z for device on USB bus 1 at address 2:

	   usbconfig -u 1 -a 2 dump_string Z

     Dump current configuration descriptor for device on USB bus 1 at address
     2:

	   usbconfig -u 1 -a 2 dump_curr_config_desc

     Dump device descriptor for device on USB bus 1 at address 2:

	   usbconfig -u 1 -a 2 dump_device_desc

     Program the device on USB bus 1 at address 2 to suspend, resume, power
     off, go into power save, or power on:

	   usbconfig -u 1 -a 2 suspend
	   usbconfig -u 1 -a 2 resume
	   usbconfig -u 1 -a 2 power_off
