[hpsdr] OZY Difficulties

[Graham / KE9H]

David:

It sounds like the VID and PID have not been programmed into your board.
PowerSDR can not see an Ozy with the default VID/PID.

Is it a TAPR "factory" board, or something that was built by you or 
someone else?

I have a procedure for programming a new board.  Let me dig it out and 
email it to
you.  It will likely be tomorrow (Monday) sometime.  I'll also get Dave 
to post it to
the support section of the Wiki.
