At work, on a Ubuntu 14.04 system, I can access my Trinket Pro without any difficulty whatsoever.
At home, using either Linux Mint or Ubuntu across two laptops, I can not communicate with the device no matter what I try.
I have the correct board selected, the correct processor, and trying to use USBTiny ISP.
Currently, I'm getting:
avrdude: ser_open(): can't open device "COM1": No such file or directory An error occurred while uploading the sketch
It's really getting frustrating having to take my devices to work just to upload a sketch, and I've been banging my head for over a week and a half. My UNO R3 boards work without issue on the same laptops.

I am running IDE version 1.8.3, with
sudo, the exact same way I'm doing at the office.
Can someone please advise on what I'm missing here? Windows is not an option; I haven't used it in many years. I'd just like to figure out what's wrong.
I do have an FTDI connector, but didn't have much luck with it either, and to be honest, don't want to use it as I just want to plug the Trinket in, and upload.
Update: I've tried both USB2 and USB3 ports repeatedly with the same results.
