== NAME

ykushcmd - control application for Yepkit YKUSH Switchable USB Hub board


== SYNOPSIS

*ykushcmd* [board_name] [*-s* _serial_number_] [OPTIONS] ...


== DESCRIPTION

*ykushcmd* allows you to control the ports of a Yepkit YKUSH
Switchable USB Hub board.

=== Board names

 ykush          YKUSH board
 ykush3         YKUSH3 board
 ykushxs        YKUSHXS board

The [board_name] must be provided for commands addressed for a specific
board.

For general or common commands, applicable to all board models, the
[board_name] has to be omited from the command.


=== YKUSH board options

*-d* 1|2|3|a

  Power Down/Off downstream port with the number privided.

  If [a] is provided as the port number then all ports will be switched.

*-u* 1|2|3|a

  Power Up/On downstream port number downstream_number

*-s* serial_number

  Board serial number to which the command is addressed.

  When multiple YKUSH boards are connected to a host, this option
  should be used to specify the board. If more than one board is
  connected and this option is not provided the command will be sent to
  the first board in the USB enumeration list.

*-l*

  Lists the serial numbers of the YKUSH boards attached to the host.

*-g* 1|2|3

  Show state of a downstream port.

*-h*

  Display help for YKUSH board specific commands.

=== YKUSH3 board options

*-d* 1|2|3|a

  Power Down/Off downstream port with the number privided.

  If [a] is provided as the port number then all ports will be
  switched.

*-u* 1|2|3|a

  Power Up/On downstream port number downstream_number

*-s* serial_number

Board serial number to which the command is addressed.

  When multiple YKUSH boards are connected to a host, this option
  should be used to specify the board. If more than one board is
  connected and this option is not provided the command will be sent to
  the first board in the USB enumeration list.

*-l*

  Lists the serial numbers of the YKUSH boards attached to the host.

*-g* 1|2|3

  Show state of a downstream port.

*-c* <port-number> <config-value>

  Configure the default state of a downstream port
  (port-number=1|2|3|e) at power-on. The port number <e> refers to
  exteranl 5V port.

  The default states are off (config-value=0), on (config-value=1) and
  persistent (config-value=2).

*-on*

  Switch On the 5V output power port.

*-off*

  Switch Off the 5V output power port.

*-r* 1|2|3

  Read GPIO with the number provided (1, 2 or 3).

*-w* 1|2|3 0|1

  Write to the GPIO with the number provided (1, 2 or 3).

  Writing a value of 1 or 0 will drive the GPIO to logical high or low,
  respectively.

*--gpio* enable|disable

  Enable / Disable GPIO control interface. Will become active on next
  reset/power-on.

*--reset*

  Resets (reboot) the YKUSH3 board.

*-h*

  Display help for YKUSH board specific commands.

*--bootloader-version*

  Board bootloader version.

*--firmware-version*

  Board firmware version.

*--boot*

  Enter bootloader mode for firmware update.

=== YKUSHXS board options

*-d*

  Power Down/Off the downstream port.

*-u*

  Power Up/On the downstream port

*-s* serial_number

  Board serial number to which the command is addressed.

  When multiple YKUSHXS boards are connected to a host, this option
  should be used to specify the board. If more than one board is
  connected and this option is not provided the command will be sent to
  the first board in the USB enumeration list.

*-l*

  Lists the serial numbers of the YKUSHXS boards attached to the host.

*-g*

  Show state of the downstream port.

*-h*

  Display help for YKUSHXS board specific commands.
