* 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([email protected]) |
|
* 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. |
