Final answer:
If you see only Automatic Selection when selecting the communications port for downloading firmware to your VEX EDR, it means the software cannot detect a specific port. You can proceed with Automatic Selection, and the software will find the appropriate port automatically.
Step-by-step explanation:
When selecting the communications port to download firmware to your VEX EDR, if you ONLY see Automatic Selection as an option, it means that the software is unable to detect a specific port to use. This usually happens if the necessary drivers are not installed or if there are multiple ports that could potentially be used. In this case, you can proceed with the Automatic Selection option, and the software will try to find and use the appropriate port automatically.
