Generic USB driver for report based interrupt in/out devices like LD Didactic's USB devices. LD Didactic's USB devices are HID devices which do not use HID report definitons (they use raw interrupt in and our reports only for communication).

This driver uses a ring buffer for time critical reading of interrupt in reports and provides read and write methods for raw interrupt reports (similar to the Windows HID driver). Devices based on the book USB COMPLETE by Jan Axelson may need such a compatibility to the Windows HID driver.
