It was the USB Hub! Using a straight through USB extension works with all my fobs, with a cheapo 4-way hub the device is reported to the system, but no audio comes through. So now I'm feeling silly, because I'm sure I checked it without the hub at some point. Anyway, I thought I'd feed back what the eventual resolution was - and I rebuilt my OS for nothing!

So the plot thickens ...
A 'StarTech.com USB to Stereo Audio External Sound Card' turned up, looking identical to the one identified by Corey.
Documentation says the chipset is 'C-Media CM108AH', and indeed when I break the case open there's a nice SMT CM108AH with exposed leads that I can hack if I go that route.
lsusb reports it as 'ID 0d8c:013c C-Media Electronics, Inc.'
But ... still no audio!!!!!
In desperation, I resinstall everything from the ACID disk I got from allstarlink.org, and lo-and-behold it works! And, all of the other fobs work too.
Anyone want a USB Soundcard?
Still no idea why it didn't work first time round, but there we go.
Many thanks for all your help,
