TLV320AIC3254EVM-U: TLV320AIC3254EVM-U not working in Windows 7

Part Number: TLV320AIC3254EVM-U


Hi,

I just bought a TLV320AIC3254EVM-U USB audio module and installed the GUI utility from the TI website. When the application starts it can see the firmware version of the device but nothing else. I can't see any of the other data pages or make any changes to the device settings. The device receives audio into Windows and can play sounds happily. The push button and LED do all the right things but the TI application can not see the device.

I have tried running the application in Win XP SP3 compatibility mode as suggested in the user guide but it's still not working.

Any advice please?

Russ
