Starting out new with USB can be quite daunting. With the USB 2.0 specification at 650 pages one could easily be
put off just by the sheer size of the standard. This is only the beginning of a long list of associated standards for
USB. There are USB Class Standards such as the HID Class Specification which details the common operation of
devices (keyboards, mice etc) falling under the HID (Human Interface Devices) Class - only another 97 pages. If
you are designing a USB Host, then you have three Host Controller Interface Standards to choose from. None of
these are detailed in the USB 2.0 Spec.
