[hpsdr] OZY Difficulties

[David M. Witten II]

Graham,

Thanks.  My strong suspicion (and hope) is that something that I did 
early on klobbered the configuration on the USB chip.  It is a TAPR 
'factory' board, but it is from before the time when the configuration 
had been worked out to make Ozy function as a ByteBlaster.

I do have JTAG tools, etc.
