usbTTY devices missing

Post by LikeTheSandwich »

When using certain types of microcontrollers (like Arduino, among others) that would normally show up as "ttyUSB*" they simply don't exist in /dev. Lsusb shows the devices, so Linux knows they are connected. Dmesg shows that it connects to ttyUSB0 then disconnects. "acmUSB" devices work just fine, I have numerous other microcontrollers in this category without issue. I have none of these issues on Linux Mint 20.3, even just in the boot environment this works fine, so it doesn't appear to be any sort of hardware issue, it must be something in Mint 21. Are there alternative kennels I can try? Where might I find such to test?

Thank you for the suggestion. I tried it a while ago but the problem is as I said, the device doesn't exist in the /dev folder, So it's not a permission's issue.
