We have just bought an AD9528/PCBZ Evaluation Board. I have followed the instructions from https://wiki.analog.com/resources/eval/ad9528-user-guide#pc_connections, but the board is not recognised by my Windows 7 PC.
After connecting the wall power supply P500,
- The red LED labelled 3V3_USB (DS4) illuminates,
The green LED labelled RESETB (DS3) illuminates
But additionally the green LED DS5 illuminates. When I next connect the USB to my PC, only the red LED labelled CR300 illuminates, but my PC is unable to instal the driver: "unknown device". My problem seems to be related to AD9548 USB driver problem. with a different board. I have installed the "USB Eval Board Programmer" from https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-AD9528.html#eb-documentation, but it can not find the board, event if I remove the EEPROM ENABLE jumper. With or without jumper, the unknown device is USB\VID_0456&PID_EE24&REV_0001.
Edit: I have also tried on another Windows 7 PC, then on an old Windows XP PC, without success. To be complete, we have bought two Eval boards, and both have the same issue.
