A hardware problem?
Hi, we maked 30 samples for our design with CY68013A, and we got 7pcs sample can not work. 4 of them with "unkown usb device" when i plug it into PC. The other 3 of them with PB or PD port can not be controlled to hight or low. That's a very low and a unbeliveable yield for a simicondoctor product in my mind. If there is a possible for software or driver problem? or just a hardware problem?
