To answer my own inquiry, I have just discovered this outfit in New York state that sells a number of USB building blocks. Maybe this might be a shortcut to a means to get digital i/o via the USB port?

Carl,

I have been using PP for PTT and COR, etc, works VERY well.

You need to have used source code, specifically app_rpt.c and chan_usbradio.c that is from after about Sept 14

Before that it didn't work.

I want to write up a cookbook process for what I did with it, just need time, like I want to put together a how to for Limey, as I had modified it, but time is a problem...

 
Hello,
 
What is the problem with those USB fobs?  Is it that they are epoxy blobbed?
 
If they are packaged chips, is it because they are not CM108?  What chip are 
they?  Please post the vendor ID/Product ID info.  I have been working with 
CM108 compatible chips- maybe I can contribute something useful here.
