Hello,

I just received a EVAL-ADUSB2EBZ adapt board to drive the eval kit EVAL-ADAU7118Z kit.

If I plug it on my windows10 computer, Windows does not detect it, and does not print message for installing driver.

All LED (D1, D2, D3 and D4) are on.

I watched the i2c signals of the eeprom and it seems to read the firmware correctly.

Is it a known problem, did I forget something ?

Thanks

Hello Martoni,

Have you installed SigmaStudio? The installer will install the correct drivers.

If not then try to re-install it.

Hi Dave,

Recently I un-installed one of the older SigmaStudio versions and the uninstall took out the USBi driver, despite that newer SigmaStudio versions remained. I had to re-install the latest version to get the driver back. The Device Manager helped troubleshoot this. It should look like this

Best regards,

Bob
