EVAL-AD5668 USB connection problem

Hi,

I have a problem with connecting Eval-AD5668 with the EVAL-SDPCB1Z adapter.

Jumper settings are at their default position. 

Here is what I did.

  1. Power both AVDD (5.5V)and DVDD (5V)
  2. Open evaluation SW without connecting the board
  3. "ERROR CONNECTION" message pops up
  4. Connect USB cable and press 'Rescan'
  5. It detects the board.
  6. Press Select
  7. "ERROR CONNECTION" message pops again and SW crashes

I installed https://www.analog.com/media/en/evaluation-boards-kits/evaluation-software/EVAL_AD5668EBZ_V4.1.zip and tested in Windows 7 and 10 but both failed.

Tech support suspects that EVAL-AD5668 board's EPROM may be incorrect and it may be reprogrammed with the correct Vendor ID string with ACE software.

Does anyone have a similar issue and solution?

Regards,

Seyoung
