Usbview shows two devices as it should.
Device Manager shows a USB device and a comport, along with a USB Audio Codec and two HID devices.
All this stuff seems to work correctly whereas with the previous one I didn't see the USB Audio codec.
Something seems to be going bad when dealing with the tuner. The previous unit communicated with the tuner just fine. I don't hear the relay click on or off on this one.
I'm leaving town immediately after work today, so I won't be able to mess with this again until next week.
