TLV320AIC3104EVM-K: Invalid Vendor & Product ID on USB-MODEVM Interface

Part Number: TLV320AIC3104EVM-K

I have a new TLV320AIC3104EVM-K, the USB-MODEVM interface board is returning invalid values for Vendor ID (0xFFFF) & Product ID (0xFFFE),

I am using Windows 7 Professional & have also confirmed the values with a Linux PC.

I have tried multiple cables to eliminate that as a problem.

I have not changed any jumpers.

On board LEDS

D2 OFF

D3 GREEN

D4 GREEN

D5 RED

D6 OFF

D7 GREEN

D8 GREEN

Any help with this problem is greatly appreciated.

Lee.

    Hi, Lee,

    Welcome to E2E and thank you for your interest in our products!

    It seems that the EVM is not correctly initialized. Probably the driver is marked as DFUUSB. So, I would recommend several steps:

    - Ensure that the EVM switches and jumpers are placed in default state as mentioned in the User's Guide.
    - Then, initialize the EVM with the indications of the E2E thread below:
