-* Common Header File for the Elan Digital Systems U132 adapter
-* this file should be included by both the "ftdi-u132" and
-* the "u132-hcd" modules.

-*
-* The driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
-* based on various USB client drivers in the 2.6.15 linux kernel
-* with constant reference to the 3rd Edition of Linux Device Drivers
-* published by O'Reilly
-*
-* The U132 adapter is a USB to CardBus adapter specifically designed
-* for PC cards that contain an OHCI host controller. Typical PC cards
-* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
-*
-* The U132 adapter will *NOT *work with PC cards that do not contain
-* an OHCI controller. A simple way to test whether a PC card has an
-* OHCI controller as an interface is to insert the PC card directly
-* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
-* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
-* then there is a good chance that the U132 adapter will support the
-* PC card.(you also need the specific client driver for the PC card)
-*
-* Please inform the Author and Maintainer about any PC cards that
-* contain OHCI Host Controller and work when directly connected to
-* an embedded CardBus slot but do not work when they are connected
-* via an ELAN U132 adapter.
-*
-* The driver consists of two modules, the "ftdi-u132" module is
-* a USB client driver that interfaces to the FTDI chip within
-* the U132 adapter manufactured by Elan Digital Systems, and the
-* "u132-hcd" module is a USB host controller driver that talks
-* to the OHCI controller within CardBus card that are inserted
-* in the U132 adapter.
-*
-* The "ftdi-u132" module should be loaded automatically by the
-* hot plug system when the U132 adapter is plugged in. The module
-* initialises the adapter which mostly consists of synchronising
-* the FTDI chip, before continuously polling the adapter to detect
-* PC card insertions. As soon as a PC card containing a recognised
-* OHCI controller is seen the "ftdi-u132" module explicitly requests
-* the kernel to load the "u132-hcd" module.
-*
-* The "ftdi-u132" module provides the interface to the inserted
-* PC card and the "u132-hcd" module uses the API to send and receive
-* data. The API features call-backs, so that part of the "u132-hcd"
-* module code will run in the context of one of the kernel threads
-* of the "ftdi-u132" module.
