I just got my Heltec V4 today, but after a few hours of trying I simply cannot flash meshtactic on it. I've only tried v2.7.x versions.

I consistently get "NetworkError: Failed to execute 'open' on 'SerialPort': Failed to open serial port"

I've tried all combinations mentioned in this thread but nothing seems to work.

I am on Linux mint, I've tried both chromium and chrome, I've tried different usb-cables (both A-C and C-C, all with verified data connections)

I can see the device with lsusb as "Espressif USB JTAG/serial debug unit"

Anyone know where I need to look for a solution? This has been a seriously shitty start to my meshtastic adventure.

I'm gonna be pissed if this fixes my issue lol, I'm supposed to already be in the damn dialout group (and as such can flash my baofeng through CHIRP; and my t114, and my sensecap tracker with the webflasher.) I'll boot up later and check.
