Thank you. That's got to be it. I've been doing debian Linux since
right around 2000 but I must admit that I don't know the easiest
way to include the patch referenced in the second link.
I will need to do that on an i86 box plus the Raspberry Pi
I first discovered the issue on since I am apt to have the radio
connected to either system and, if this problem is fixable, this
solution is preferable because the radio defaults to using the
usbC port as the serial port so it should still work if a full
reset is ever needed and the mechanism for usb should naturally
accept as many different devices as practical because you never
know what you will need to connect until you try it and it fails.
As an amusing aside, the radio has a usb mode, but
that's totally unrelated because in that case, USB stands for
upper side band and is a very energy-efficient method of radio
communication because it is only a spectrum of frequencies
consisting of the sidebands of an audio signal without the
carrier. It can be LSB or lower side band or USB for upper side
band. Nothing like a few new acronyms for your day. I guess that's TMI.
