MSP430F5529: MSP430F5529 Not Enumerating Solved

Part Number: MSP430F5529

MSP430F5529 Not Enumerating Solved.

Hi all, I wanted to post a question and answer here since I have seen many people having an issue with the MSP430F5529 not enumerating.

The demo board uses a USB hub and so have a few other reference designs I've seen, for the most part those seem to work fine...I'm specifically addressing the people not using a hub and going strait from the MSP430 to a USB connector.

Remove the 10pF caps that so many reference designs call out. They trip up the timing of the USB comms so the PC goes right into idle mode.

If you don't have this problem, great but if you do might I suggest removing the caps before tearing out all of you hair first.

The MSP seems extremely sensitive, even my oscope probe on the D- line caused the MSP430 to not enumerate.
