Re: [chirp_users] Dumb 8900 queary

/dev/ttyUSB0 /dev/ttyUSB1 That's the 2 Ext HD partitions.

No, those are USB-to-serial adapters.

I'll see if I can get someone to check (wiggle) the plugs

They're clearly connected and identified by the OS. Have you tried CHIRP against both of them?

(I have 5% use of 1 hand)

For what it's worth, all of the Icom radios are fully remotely addressable. That means you plug in the radio and CHIRP does the rest. It can place the radio into clone mode in both directions and handle multiple clone upload/download operations without you ever touching the radio. They don't make something to compete with the 8900, but I just thought I'd point that out.
