I am considering using a LPC1768 and I've noticed that many (if not all) LPC's with USB OTG have an errata regarding a problem that causes the chip to hang in USB host mode if a dribble bit is encountered.

The errata implies that this happens if there is a hub between the LPC and the device.  Am I immune from this problem if there is no hub?

Do the currently shipping revisions of the LPC1768 (or any LPC17xx) have this problem fixed?

Hello sarmitage,

Sorry, no solution yet ... otherwise the work-around could be: not to use a hub ...
