Question from Judy: Hi, Rick. I have a tech question for you.
There are so many USB transmitters now that it’s easy to lose track of which transmitter goes to which device.
I can make out the Model and Serial numbers on the transmitters, but they never match the device model/SNs.
Is there any way to determine which transmitter goes to which device other than a hit-or miss series of tests?
Rick’s answer: I know exactly what you mean Judy, because I’ve assembled quite a collection of wireless USB devices of my own.
And I do have a very simple (and extremely low-tech) solution: Nail Polish!
Get yourself several bottles of nail polish (the cheapest you can find will work just fine) and use them to mark both the devices and the transmitters that are paired with them with a dab of polish.
You don’t need to “paint” the devices. Just a single drop on the bottom or side will suffice.
For example, you could put a drop of white nail polish somewhere on your wireless mouse and another drop on its transmitter. From that day forward you’ll always know that the transmitter with the white dot is paired with the mouse with the white dot.
Have a wireless keyboard? Put a drop of yellow nail polish on the bottom of it and another drop on its transmitter.
If you ever find yourself in possession of more devices than you have colors, you can use the colors in pairs.
For example, after you run out of different colors to use you could use a drop of white AND a drop of yellow to “match up” the next device with its transmitter.
If you have several different colored nail polishes on hand you could use them in pairs to “match up” dozens of wireless USB devices (even though it’s unlikely you’ll ever have that many).
I hope this helps, Judy. Good luck!
