USBi random disconnections?

Hi All, first post here and unfortunately it's to report a fault.

 

I have just received the EVAL-ADAU1761Z and it's all very lovely.

 

Some times the SigmaStudio will loose contact with the USBi device. The ADAU1761 chip continues to function however I am unable to control it or reprogram the device without unplugging the USB cable (power cycle) - reinserting and waiting for about 10 seconds.

 

I run Windows 7 ( all the latest updates ) on a 2 year old Macbook Pro

 

I have attached a number of images below.

 

I've searched the forum and found at least one other post related to this... do I need a new USBi or eval board?

 

Thanks
