COM port & USB troubleshooting
« on: 2017-04-19, 04:04:00 »
Hi All,

Recently there has been plenty of discussion regarding USB/Serial/COM port troubleshooting. It can be difficult to guess at what the problem can be in these situations and plugging/unplugging cables can be frustrating.

Some time ago I had some problems with a USB serial connection from a radio to my PC. It stopped me from connecting to my logging program. However I found a FREE product that allowed me to view the comms on this serial line and with that I was able to find a coding error in a configuration file.

While I was searching for a solution I also came across a very neat tool that allowed me to view all installed/connected USB devices on my system. Every wondered why your new USB serial cable comes up as COM 26 or higher? Ever wondered why your USB device is not recognized? This tool will show you why this happens and give you a way to fix it.

I am sure that these tools can help to investigate RRC/USB connection issues as well as many other comms issues you might have.
