Did you check the forum WIKI and FILES sections for notes on how to connect the nano to a Linux system?

Hello,
I'm relatively new to the group and this is my first post. I would like to run some VNA software - specifically, NanoVNA-saver - in a Linux (Skywave 3.1.1) virtual machine from a Mac OS X host, using Virtual Box. Usually one connects USB devices from the host to the virtual machine from a Devices pull-down menu. When I attempt to do this with the NanoVNA, I get the message "Failed to attach the USB device STMicroelectronics Chibi OS/RT Virtual COM Port [0200] to the virtual machine Skywave 3_1_1."? When looking at the details for the error. I see 'USB device STMicroelectronics Chibi OS/RT Virtual COM Port' with UUID {a5a2dd91-efd1-42ce-a9c0-7ab458ad2ec9} is in use by someone else." Usually a message like this means that the USB device is in use by another program on the Mac host, but in this case there I have no application launched on my Mac host using the NanoVNA .
I get a similar error message when I try to connect the NanoVNA to a virtual XP machine in Virtual Box.
Has anyone been here before who can lend some help and guidance? For example, is there a terminal command I can execute in the host to get my Mac to "let go" of the device?
Thanks,
