won't enumerate on all USB 2.0 PCs

I have a laptop where the FX3 will not enumerate. It never returns from CyU3PConnectState(CyTrue,CyTrue). CyU3PConnectState(CyTrue,CyFalse) works everytime.

Other USB 2.0 machines enumerate correctly.

I am using API version number = 1.0.1.670.

By any chance did you hook up a CATC to look at what is going on the USB bus and where exactly it is failing?

Regards,

Anand

I don't have access to an external analyzer. All I know is it never returns from CyU3PConnectState.
