The receiver self-identifies as a - * "USB Receiver" with manufacturer "X10 Wireless Technology Inc". - * - * The "Lola" remote is available from X10. See: - * http://www.x10.com/products/lola_sg1.htm - * The Lola is similar to the ATI remote but has no mouse support, and slightly - * different keys. - * - * It is possible to use multiple receivers and remotes on multiple computers - * simultaneously by configuring them to use specific channels. - * - * The RF protocol used by the remote supports 16 distinct channels, 1 to 16. - * Actually, it may even support more, at least in some revisions of the - * hardware. - * - * Each remote can be configured to transmit on one channel as follows: - * - Press and hold the "hand icon" button. - * - When the red LED starts to blink, let go of the "hand icon" button. - * - When it stops blinking, input the channel code as two digits, from 01 - * to 16, and press the hand icon again. - * - * The timing can be a little tricky. Try loading the module with debug=1 - * to have the kernel print out messages about the remote control number - * and mask. Note: debugging prints remote numbers as zero-based hexadecimal. - * - * The driver has a "channel_mask" parameter. This bitmask specifies which - * channels will be ignored by the module. To mask out channels, just add - * all the 2^channel_number values together. - * - * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote - * ignore signals coming from remote controls transmitting on channel 4, but - * accept all other channels. - * - * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be - * ignored. - * - * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this - * parameter are unused. - * - */ - -#include <linux/kernel.h> -#include <linux/errno.h> -#include <linux/init.h> -#include <linux/slab.h> -#include <linux/module.h> -#include <linux/moduleparam.h> -#include <linux/usb/input.h> -#include <linux/wait.h> -#include <linux/jiffies.h> - -/* - * Module and Version Information, Module Parameters - */ - -#define ATI_REMOTE_VENDOR_ID 0x0bc7 -#define ATI_REMOTE_PRODUCT_ID 0x004 -#define LOLA_REMOTE_PRODUCT_ID 0x002 -#define MEDION_REMOTE_PRODUCT_ID 0x006 - -#define DRIVER_VERSION "2.2.1" -#define DRIVER_AUTHOR "Torrey Hoffman <thoffman@arnor.net>" -#define DRIVER_DESC "ATI/X10 RF USB Remote Control" - -#define NAME_BUFSIZE 80 /* size of product name, path buffers */ -#define DATA_BUFSIZE 63 /* size of URB data buffers */ - -/* - * Duplicate event filtering time. - * Sequential, identical KIND_FILTERED inputs with less than - * FILTER_TIME milliseconds between them are considered as repeat - * events.
