Uniden Programming on Linux

[N6JPA]

I have the BC125AT plugged into a USB port on my Linux Computer. When I list 'lsusb' the BC125AT is listed. When I list the /dev folder for 'tty' links there is no 'ttyUSB#" listed in the directory. I know on windows it is a comport, where do I connect to the BC125AT using Linux? TIA.

If you don't see a device such as /dev/ttyACM0, check the output of dmesg to see if contains further details.

Okay I get error -22 when I plug in the BC125AT to the USB port on the desktop computer. Here is the full dmesg:

Any ideas how to fix the issue?

I'm using Linux Mint 21.3.

TIA.

It seems that the BC125AT has a "quirk" in the USB interface which must be accounted for in the Linux kernel driver.

According to a 2023 post on the Linux Mint Forums, the fix was not included in Linux Mint 21.1, and it may be that 21.3 is the same. If you're already running the latest kernel for 21.3, this probably is indeed the case.

You'll need a kernel that includes the fix. You can try upgrading to the latest version of Linux Mint to see if that works. You can also boot a live image on your PC instead. I used Fedora when I programmed my BC125AT.
