Fixed possible invalid program execution when in host mode if corrupt descriptor lengths are supplied by the attached device.
Minor code cleanups to add const and reformat where missing, as well as abstract out the internal device signature start address into a macro, so that it can be altered to suit particular devices within a single architecture if needed.
Add missing documentation to the USB_Device_States_t enum.
