- Say Y here if you want to use an ATI or X10 "Lola" USB remote control.
- These are RF remotes with USB receivers.
- The ATI remote comes with many of ATI's All-In-Wonder video cards.
- The X10 "Lola" remote is available at:

- This driver provides mouse pointer, left and right mouse buttons,
- and maps all the other remote buttons to keypress events.

- * USB ATI Remote support
- *
- * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
- * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
- *
- * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
- * porting to the 2.6 kernel interfaces, along with other modification
- * to better match the style of the existing usb/input drivers. However, the
- * protocol and hardware handling is essentially unchanged from 2.1.1.
- *
- * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
- * Vojtech Pavlik.
- *
- * Changes:
- *
- * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
- * Version 2.2.0
- * Jun 2004: Torrey Hoffman <thoffman@arnor.net>
- * Version 2.2.1
- * Added key repeat support contributed by:
- * Vincent Vanackere <vanackere@lif.univ-mrs.fr>
- * Added support for the "Lola" remote contributed by:
- * Seth Cohn <sethcohn@yahoo.com>

- * Hardware & software notes
- *
- * These remote controls are distributed by ATI as part of their
- * "All-In-Wonder" video card packages. 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.
- *

+ * Hardware & software notes
+ *
+ * These remote controls are distributed by ATI as part of their
+ * "All-In-Wonder" video card packages. 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.
