Description

The USB endpoint descriptor macros for taking apart the max bytes per packet and the maximum burst, or the maximum number of packets that can be used in a given frame is incorrect in uts/common/sys/usb/usbai.h.

The problem is that it incorrectly assumes how many bits are related to the max packet size and the burst. See USB 2.0 section 5.9.
