+* 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.
+*

+*(tony.olech@elandigitalsystems.com)
+*
+* 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.
