ykushcmd - control application for Yepkit YKUSH Switchable USB Hub board
ykushcmd [board_name] [-s serial_number] [OPTIONS] ...
ykushcmd allows you to control the ports of a Yepkit YKUSH Switchable USB Hub board.
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.
-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.
-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.
-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.
