[hpsdr] EEPROM Programming

[Scott Cowling]

Hi Phil,

How long does it take to program a new blank chip via the USB interface?

As others have suggested, we could have the parts pre-programmed 
before we install them. However, we need to test the assembled PCBs 
anyway, so it might make sense to just program them at that time if 
it not too time consuming.
