LPC4357 HS USB Bulk IN Endpoint issue.

Does the LPC4357 - ROM for USB Devices support USB HS Device custom classes ? Or do i need to find a non-ROM device stack to handle the host connection. The LPC4357 will be the custom class accessory, the iPhone will be the host. After enumeration the LPC4357 doesn't get any IN data (events) on the IN bulk endpoint. I have registered the BULK endpoint handlers, and a classHandler. Still don't see BULK IN events. The USB anaylzer shows the host making a BULK IN attempt. Seems my BULK IN endpoint isn't enabled or something ? Any clues ?
