In reference to AN11018

Is there difference in USB interface hardware and register layout including between LPC13xx and LPC15xx?

The LPCopen only have ROM based USB library, I'm looking for non ROM library collection that work for LPC15xx and wondering if I can use LPC13xx library for that?

R.

There's no way you can use LPC1343 code. The USB block of LPC1549 uses a totally different concept, and you would have to completely re-write all lower layer code.

so it not possible to use non-rom USB code (composite MSC+CDC) from 1343 into 1549 device.

I'm running out of option with no expert help. I unable to get MSC+CDC composition working on 1549 device. I posted code sample for 1549 expresso board which has MSC working and CDC working alone but fails on MSC+CDC composite.

LPC15xx uses the same USB block as the LPC1345/46/47.
Note that the older LPC1343 is completely different!
