COM Ports Not Apppearing

Hardware Support
1

I cannot get any of my Adafruit products to appear as a com port on my PC. I have tried finding the drivers for all my respective parts and MOBO. I have had it work before with the exact same setup but it will randomly not work and I do not know why. Any Ideas?

Welcome! :smile:

Is the driver a CH340? I've had issues with this one and other Ubuntu systems. Here are the downloadable 1.6.x drivers, not sure if you've already got those or not.

With it in USB, what do you get with lsusb?

This is what lsusb throws up:

Was hoping for a ID of some kind :sweat_smile: I don't see it though..

Do you get any notification sound when plugging in? :thinking: If you are using pin-outs to connect, check the TX / RX wires - my USB breakout cable likes to baaaarely hit the pins sometimes :expressionless:

Doing some digging..

I'm stepping away for a moment - I do see an arduino package available in apt, I don't know if you've got that installed; has built-in libraries, might be good.

Also I see a USB hub in there - are you plugging into the 3rd from the bottom in the list - the USB2.0 Hub? May or may not be hindering some communication to it through the hub.. I would also suggest installing libusb-dev for better support on USB devices.
