1. Re: fx3 enumerate as UNKOWN DEVICE, driver don't install
user_512410720 Sep 2, 2015 12:02 AM (in response to paulsons)Did you find a solution to this problem?
I have exactly the same issue. My prototypes fail enumeration. All power supplies and communications connections are good. Like you, I am using an external oscillator (ASEMB-19.2MHZ) connected to the CLKIN input. I have also configured the FSCLK[2:0] pins to be 100.
Perhaps there is a problem using an external oscillator instead of a crystal. Can anyone provide any input here please?

naz Sep 3, 2015 1:25 PM (in response to paulsons)My fast enumeration usb setup callback does not handle host requests or usb events properly (yet). So, every time I do something wrong on the host side, my device starts being unknown to the PC. The only way, I found, to get it recognized again was to restart the PC.

If no solution has been found: did you make sure your PMODE[2-0] pins were configured correctly for the proper boot operation?
