USB Host examples on LPCXpresso546xx - RevC

I have an LPCXpresso546xx RevC board with an LPC54628 chip on it. I have been trying to get USB host working but am having no success with the MCUXpresso 3.2.0 SDK examples.


I can get device examples working no problem but the host examples all say "host init done" and then sit there doing nothing. Putting breakpoints at various points eg. the kUSB_HostEventAttatch case never trigger.


I have used various leads and tried various examples. I can see the High Speed port powers up but that is it.


Has anyone else seen these examples work?


Also it is not clear to me how I would configure these examples to run on the Full speed interface (as will eventually be needing). The device examples are all obvious in the usb_device_config.h file.
