[chirp_users] Download From Radio under Ubuntu 20.04 error

[Robert Withers]

Hi Eric,

Thanks for pointing me this way, although it seems I am not auto configuring a module for ttyUSB0. I am attaching the output of

> lsmod | sed -n 'p;$=' > lsmod-count.txt

Where the last line is a line count. There is no changes in this output between having the phoe unplugged versus plugged, so perhaps that is an indicator that auto-config of a module to talk to the radio is misfiring. I dunno. Is this where modprobe comes in? What module name should I install for Chirp managing traffic over ttyUSB0?

Thanks!
Robert

This was the gnome project idea of mimicking a windows interface as well as it’s control panel. However, it is sometimes not as useful as being able to troubleshoot and add/remove devices from the CLI. One should look up lsmod as well as modprobe and Insmod. If things are working correctly, new devices will always appear in the /dev directory and may even have some sort of “magic number” associated with them. That’s an advanced idea and shouldn’t really be of concern for this discussion.

After plugging in the cable that connects to your radio, and doing the same command, you should see 1 or more new modules loaded. Those modules will be associated with new devices that show up under /dev. Now, they may be listed as TTYS0 or TTYS1, etc. those would be your comm port entries. ttys0 should be associated with comm 1, etc.

However, there may be some cases where you may have to add your user account to the appropriate group in order to use the device. There are GUI programs for this as well as some CLI commands. Now, some of the commands above may require that you use sudo and log into root. 2 items of caution here:
