17 * The driver was written by Tony Olech([email protected])
18 * based on various USB client drivers in the 2.6.15 linux kernel
19 * with constant reference to the 3rd Edition of Linux Device Drivers
20 * published by O'Reilly
21 *
22 * The U132 adapter is a USB to CardBus adapter specifically designed
23 * for PC cards that contain an OHCI host controller. Typical PC cards
24 * are the Orange Mobile 3G Option GlobeTrotter Fusion card.
25 *
26 * The U132 adapter will *NOT *work with PC cards that do not contain
27 * an OHCI controller. A simple way to test whether a PC card has an
28 * OHCI controller as an interface is to insert the PC card directly
29 * into a laptop(or desktop) with a CardBus slot and if "lspci" shows
30 * a new USB controller and "lsusb -v" shows a new OHCI Host Controller
31 * then there is a good chance that the U132 adapter will support the
32 * PC card.(you also need the specific client driver for the PC card)
33 *
34 * Please inform the Author and Maintainer about any PC cards that
35 * contain OHCI Host Controller and work when directly connected to
36 * an embedded CardBus slot but do not work when they are connected
37 * via an ELAN U132 adapter.
38 *
39 * The driver consists of two modules, the "ftdi-u132" module is
40 * a USB client driver that interfaces to the FTDI chip within
41 * the U132 adapter manufactured by Elan Digital Systems, and the
42 * "u132-hcd" module is a USB host controller driver that talks
43 * to the OHCI controller within CardBus card that are inserted
44 * in the U132 adapter.
45 *
46 * The "ftdi-u132" module should be loaded automatically by the
47 * hot plug system when the U132 adapter is plugged in. The module
48 * initialises the adapter which mostly consists of synchronising
49 * the FTDI chip, before continuously polling the adapter to detect
50 * PC card insertions. As soon as a PC card containing a recognised
51 * OHCI controller is seen the "ftdi-u132" module explicitly requests
52 * the kernel to load the "u132-hcd" module.
53 *
54 * The "ftdi-u132" module provides the interface to the inserted
55 * PC card and the "u132-hcd" module uses the API to send and receive
56 * data. The API features call-backs, so that part of the "u132-hcd"
57 * module code will run in the context of one of the kernel threads
58 * of the "ftdi-u132" module.
