I could really use some help here - is my device bricked?

Problem using the SparkFun Pro Micro C fresh out of the anti-static bag

Using a USB A to C cable

Will not connect to the Windows or Mac or Linux PC

Windows complains that the descriptor is not available

Linux does not show a device connect - only if I put into boot mode

Linux Debug capture

I personally think the original Arduino Micro is more convenient. https://www.theengineeringprojects.com/ … micro.html

However, regarding your problem, it can be a bad board or a bad cable. If it is possible for you, I suggest you try with another USB A to C cable. Such errors can also occur if the bootloader is wiped off,

Excellent comment - thank you for your recommendations.

I forgot to mention that I tried several USB - C cables (C-C, A-C) with the same results.

I am inclined to think if the Pro Micro can communicate with the Mac/PC/Linux in bootloader mode - the cable is probably good.
