PSOC with USBUART and Win7 x64

Dear all,

I am trying to install the USBUART driver of my PSOC project under a Win7 x64 system.

Unfortunatly the generated .inf file isn't recognized by Windows..

Anyone has a clue?

Thanks, Thomas

I also tried a Win7 32bit version with the same result...

I solved it!

There was a problem with the code on the PSOC. I enabled the Global Interupts too late.

Sorry for this stupid question :)

Ha, thats a common mistake many people do in the beginning. And it is not quite apparent. Even if the Global Interrupt is enabled after USBFS_Start() the code will still work. But the enumeration process will begin once you enable the global interrupt. But if you are waiting for enmureation to be complete(or for a valid configuration to be assigned), you might get stuck there forever.
