The IAR compilier does not resolve references to fields in the anonymous structs defined within the usbh_dev0_t and usbh_device_t structs as they are defined. The problem seems to relate to the placement of the 'volatile' keyword at the struct level. I fixed the problem by removing the 'volatile' from the struct level, and instead placing it on each of the field declarations within the structs.
