I was wondering how the Kenwood TS 590SG plays with Linux. Unlike older radios, it has a USB port on it, which when plugged into a computer, provides a USB serial interface, and a USB souncard.
Kenwood supply drivers for Windows, but I wanted to know if the devices in the radio were supported by Linux.
I asked a very helpful Kenwood technician in London (thanks Geoff!) who didn't know, but passed on my request to Japan, where they booted a copy of Ubuntu 15.10, plugged in the radio, and replied with the output of dmesg and lsusb.
Many thanks to Kenwood for their help in this.

In case this helps anyone else, this is the output of dmesg for the Kenwood TS 590SG
