| 4 | * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net> |
| 5 | * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev |
| 6 | * |
| 7 | * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 8 | * porting to the 2.6 kernel interfaces, along with other modification |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 9 | * to better match the style of the existing usb/input drivers. However, the |
| 10 | * protocol and hardware handling is essentially unchanged from 2.1.1. |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 11 | * |
| 12 | * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by |

Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 46 | * These remote controls are distributed by ATI as part of their |
| 47 | * "All-In-Wonder" video card packages. The receiver self-identifies as a |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 48 | * "USB Receiver" with manufacturer "X10 Wireless Technology Inc". |
| 49 | * |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 50 | * The "Lola" remote is available from X10. See: |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 51 | * http://www.x10.com/products/lola_sg1.htm |
| 52 | * The Lola is similar to the ATI remote but has no mouse support, and slightly |
| 53 | * different keys. |
| 54 | * |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 55 | * It is possible to use multiple receivers and remotes on multiple computers |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 56 | * simultaneously by configuring them to use specific channels. |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 57 | * |
| 58 | * The RF protocol used by the remote supports 16 distinct channels, 1 to 16. |
| 59 | * Actually, it may even support more, at least in some revisions of the |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 60 | * hardware. |
| 61 | * |
| 62 | * Each remote can be configured to transmit on one channel as follows: |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 63 | * - Press and hold the "hand icon" button. |
| 64 | * - When the red LED starts to blink, let go of the "hand icon" button. |
| 65 | * - When it stops blinking, input the channel code as two digits, from 01 |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 66 | * to 16, and press the hand icon again. |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 67 | * |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 68 | * The timing can be a little tricky. Try loading the module with debug=1 |
| 69 | * to have the kernel print out messages about the remote control number |
| 70 | * and mask. Note: debugging prints remote numbers as zero-based hexadecimal. |
| 71 | * |
| 72 | * The driver has a "channel_mask" parameter. This bitmask specifies which |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 73 | * channels will be ignored by the module. To mask out channels, just add |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 74 | * all the 2^channel_number values together. |
| 75 | * |
| 76 | * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 77 | * ignore signals coming from remote controls transmitting on channel 4, but |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 78 | * accept all other channels. |
| 79 | * |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 80 | * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 81 | * ignored. |
| 82 | * |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 83 | * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 84 | * parameter are unused. |
