Add a warning about using the USB 2.0 port on Control Hubs

Using the USB 2.0 port on the REV Control Hubs can cause Wi-Fi disconnects. This is because the USB 2.0 port shares an internal bus with the Wi-Fi radio, meaning if static discharge goes through the port, it can kill the Wi-Fi. Add a warning to the website advising teams to use the USB 3.0 port and/or use a USB splitter to avoid disconnects.

Start by locating the website page that documents REV Control Hubs. Add a warning explaining that the USB 2.0 port can cause Wi-Fi disconnects and advising teams to use the USB 3.0 port and/or a USB splitter. Done means the warning is visible on the relevant page and the documentation still builds successfully.
