I try to set up the USB module in device slave mode and connect it to a Win XP pc. The first interrupt i get is DEV_STAT and the second is ERR_INT. When i get the ERR_INT I run the Get Error Code command and get error code 0x1, PID Encoding Error. What might the reason be for this error? Win XP shows the message "USB Device Not Recognized". I use a LPC1778.

I found the problem. The usb clock frequency was 60 MHz. I set it to 48 MHz and now I don't get the error.
