ADAU1701-MINIZ Communication failure

I have just received my evaluation board for ADAU1701 and been playing a few hours with it fine.


However I had some  minor trouble using it on different USB port but one was working fine so I decided to uninstall the drivers and to do the installation again.


Since then, I canno't communicate anymore with the DSP!

When I try to 'link compile download', a message box tells me that "A USB communication failure has occured".


The USBi seems to work fine since the color of the USBi title is light orange on SigmaDSP. My computer tells me that the USBi is correctly installed and all the leds seems to light up correctly on both boards.


Does anyone have any idea of the solution?


Thanks for your help
