Unrecognized USB device on HSC-ADC-EVALCZ

 

Dear Sir

 

I had purchased and used HSC-ADC-EVALCZ to collect data from an ADC Evaluation board.

It is working properly for a few days. Then one fine day, when i plug the HSC-ADC-EVALCZ, Windows 7 detect unrecognized usb device after a few days.

 

I had tried to reinstall driver, change a computer, it does not work.

I suspect it is the cypress USB prom corrupted.

May i know how to rectify/solve this?

Warmest Regards,

Alex
