Does anyone know how to fix “A device attached to the system is not functio

Tags: Operating Systems

I bought a set of Holybro v3 telemetry radios, plugged one into my pixhawk 2.1 (black cube) and the other in my windows computer set the baud rate to 57600, and I had to install a driver with zadig because my pc didn’t install one. The only one that would seemed to work is “USB serial(CDC)” so I selected com3 and hit connect and this is what I get “A device attached to the system is not functioning”. I know their communicating to each other because both are solid green with red flashing simultaneously, I’ve tried it on another pc and get the same result. Most of that probably isn’t important, but I thought it could help. Any help or suggestions from you smart people is greatly appreciated! Thank you!!

One of our business products which I authored uses old school RS232 and the USB to RS232 adapters rarely install the necessary driver.

I can’t guess if your dongle and driver are correct so I’ll share the model we are currently using on Windows 10: https://smile.amazon.com/gp/product/B00425S1H8/

If your adapter is not functional (blinking lights is NOT good enough to tell) and you can’t test it out, time to try another adapter and then back to the makers of these things.
