MC57XXPSIA Appears as Unknown Device

Other Parts Discussed in Thread: TAS5727EVM

Hi,

I have been using the MC57XXPSIA with a TAS5727EVM fine until today when I went to use it with the TAS57XX GUI and everytime I connect the board I get it appearing as an unknown device and the Windows hardware wizard obviously cannot find a driver for an unknown device.

I have tried reinstalling the TAS57XX GUI, and tried using it on other PCs to no avail.

Any idea what the problem might be?

Thanks, Rob
