[hpsdr] Problem: Ozy/USB malfunction/not recognized

[Bill Tracey]

Hmmm ... any chance the USB port is not USB2 - USB 1.1 hub 
perhaps?  Can you try a different USB cable?  Is the +5v supply on 
Atlas stiff - can you measure the current draw on the +5v line?

If it is reporting 0x0 for VID and PID something is not quite 
right.  It should be 0xfffe/0x7 (VID/PDI) if the EEPROM on Ozy is 
being recognized as programmed and 0x4b4/0x8613 if the EEPROM is not 
programmed.

If that does not do it, any chance of trying another computer to try 
and isolate it to being a computer side problem or board side problem?

Regards,
