General Description:
This header is included when we compile with the IAR C-compiler and assembler.
It defines macros for cross compatibility between gcc and IAR-cc.
Thanks to Oleg Semyonov for his help with the IAR tools port!

/* Depending on the device you use, you may get problems with the way usbdrv.h
* handles the differences between devices. Since IAR does not use #defines
* for MCU registers, we can't check for the existence of a particular
* register with an #ifdef. If the autodetection mechanism fails, include
* definitions for the required USB_INTR_* macros in your usbconfig.h. See
* usbconfig-prototype.h and usbdrv.h for details.
