Alas, yes.  I know at least that part is able to communicate since I can 
change the clock, disconnect it, restart the software and read the clock
back afterwards and see that the setting stayed put.  But other than that
I can't seem to get anything else.  

Looks like I might have to send it back.

Regardless of that, the ISP speed must be set to 1/4 (or less) of the
processor speed, else it will not program correctly. Some I've found things
will look like they work at higher speeds and fool you. If you are running
at 8Mhz on your board the ISP must be at 2Mhz or less. But I assume that you
checked that.

I just brought up and tested 2 USB AVRISP units a few days ago and they
worked fine. They are gone now in the field and I had no problems with them.
