6 | * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev | |
7 | * | |
8 | * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including | |
05f091ab | 9 | * porting to the 2.6 kernel interfaces, along with other modification |
1da177e4 LT |
10 | * to better match the style of the existing usb/input drivers. However, the |
11 | * protocol and hardware handling is essentially unchanged from 2.1.1. | |
05f091ab DT |
12 | * |
13 | * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by | |
1da177e4 LT |
14 | * Vojtech Pavlik. |

45 | * Hardware & software notes | |
46 | * | |
05f091ab DT |
47 | * These remote controls are distributed by ATI as part of their |
48 | * "All-In-Wonder" video card packages. The receiver self-identifies as a | |
1da177e4 LT |
49 | * "USB Receiver" with manufacturer "X10 Wireless Technology Inc". |
50 | * | |
05f091ab | 51 | * The "Lola" remote is available from X10. See: |
1da177e4 LT |
52 | * http://www.x10.com/products/lola_sg1.htm |
53 | * The Lola is similar to the ATI remote but has no mouse support, and slightly | |
54 | * different keys. | |
55 | * | |
05f091ab | 56 | * It is possible to use multiple receivers and remotes on multiple computers |
1da177e4 | 57 | * simultaneously by configuring them to use specific channels. |
05f091ab DT |
58 | * |
59 | * The RF protocol used by the remote supports 16 distinct channels, 1 to 16. | |
60 | * Actually, it may even support more, at least in some revisions of the | |
1da177e4 LT |
61 | * hardware. |
62 | * | |
63 | * Each remote can be configured to transmit on one channel as follows: | |
05f091ab DT |
64 | * - Press and hold the "hand icon" button. |
65 | * - When the red LED starts to blink, let go of the "hand icon" button. | |
66 | * - When it stops blinking, input the channel code as two digits, from 01 | |
1da177e4 | 67 | * to 16, and press the hand icon again. |
05f091ab | 68 | * |
1da177e4 LT |
69 | * The timing can be a little tricky. Try loading the module with debug=1 |
70 | * to have the kernel print out messages about the remote control number | |
71 | * and mask. Note: debugging prints remote numbers as zero-based hexadecimal. | |
72 | * | |
73 | * The driver has a "channel_mask" parameter. This bitmask specifies which | |
05f091ab | 74 | * channels will be ignored by the module. To mask out channels, just add |
1da177e4 LT |
75 | * all the 2^channel_number values together. |
76 | * | |
77 | * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote | |
05f091ab | 78 | * ignore signals coming from remote controls transmitting on channel 4, but |
1da177e4 LT |
79 | * accept all other channels. |
80 | * | |
05f091ab | 81 | * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be |
1da177e4 LT |
82 | * ignored. |
83 | * | |
05f091ab | 84 | * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this |
1da177e4 LT |
85 | * parameter are unused. |
86 | * | |
