    - * 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.
    - *

    + * 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.
