The hardware setup to start using YKUSH 3 is quite simple, it's connected exactly as any other USB Hub, just
connect the upstream port to the host system (eg., a PC USB port).
At this point YKUSH 3 is working as Bus Powered Hub (takes the power input from the host USB port). This
powering mode should only be used when just low power USB devices are to be connected. If higher power USB
devices (e.g., external USB HDD) are to be connected then the Self/External Powered mode (external power supply)
is recommended.
To use the advanced board functionalities a software component must be installed in the host system (or custom
developed by the user). We make available for download our control software, the
ykushcmd
. This software
component implements the communication protocol with the YKUSH 3 in-board microcontroller that controls the
board functionalities.
The control application is provided as Open Source software and can be downloaded from the YKUSH 3 product
page at www.yepkit.com.
The software provided sends commands from the host system to YKUSH 3 to perform the following actions:
●
Switch ON (bring UP) a downstream port
●
Switch OFF (bring DOWN) a downstream port
●
Get downstream port status
●
List the serial numbers of the YKUSH 3 boards connected
To make these commands available in the host system follow the instructions in the setup guide by following the link
for your system in the product page.
