difference between command line and virtual machine manager

[wf5w]

I am a newbie when it comes to QEMU/KVM. So bear with my questions.

 

To explain what I am doing, I am a ham radio operator, and need to run Winlink radio email and VARA in Windows. That is all I use windows for. Wine is not sufficient to run it for some reason that I am unable to fathom. Therefore, I have had to resort to the Virtual Machine.

 

Now on to the reason for this post:

 

My host is a fairly recent Linux Mint 21.1. My Guest is a Windows 10. My usual method is to bring up Virtual Machine Manager, and run Windows from there. It works great UNTIL I try to use the radios' USB port for data communications.

 

The radio has either a C-Media chipset or a cp210 type chipset (depending upon the radio). It has the quality of being BOTH a USB audio, AND 1 or 2 serial ports (for CAT control and PTT). What I need to do, is to pass through both the audio part and the serial port(s) part as well.

 

But they might not be present, if the particular radio is not on. Which brings me to my 2nd question, how do I start up the VM without them, if I am not plugged in to the radio's USB port. And then be able to run the VM when they ARE plugged in. Which leads me to, can I run this whole thing via the command line with or without the particular USB port, and how do I create the command line version from the Virtual Machine Manager?

 

So in summary I have 3 questions:

 

1. How to pass through the USB device in question (both audio and serial) ?

 

2. How to make it all variable (sometimes one radio vs the other will be plugged in, and sometimes none at all) ?

 

3. If different CLI versions have to be made depending upon #2 above, how do I create that from what I have in the Virtual Machine Manager?
 

I hope this ramble makes some sense to someone at 5:00 in the morning!

 

Thank you for taking the time to read this, and look forward to your answers.

QEMU linux host windows 10 guest: how to pass through cp210x or C-Media type chipsets

[wf5w]

I have a specific question here:

 

I am a amateur radio user, and in the radios I have are a combination chipset that when plugged in produce a serial device AND an audio IN/OUT device.

 

So when plugged in, I get a dmesg such as this:

 

ttyACM0 and ttyACM1 from C-Media (or cp210x) ...

and also arecord -l gives a card/device# as well.

 


using this in the linux host is straightforward with the applications that use it, but to use it in a windows 10 guest is another matter. I am not much of a windows user, but I would expect an audio device and something in the COM ports section of the device manager.

 


I am using Virtual Manager, and would like to know how to proceed with passing through a cp210x or C-Media device (both audio and serial ports)

 

Thank you in advance for your help.
