  • 652f3d00d   HID: cypress: Support Varmilo Keyboards' media hotkeys ... Browse Code »

    The Varmilo VA104M Keyboard (04b4:07b1, reported as Varmilo Z104M)
    exposes media control hotkeys as a USB HID consumer control device, but
    these keys do not work in the current (5.8-rc1) kernel due to the
    incorrect HID report descriptor. Fix the problem by modifying the
    internal HID report descriptor.

    More specifically, the keyboard report descriptor specifies the
    logical boundary as 572~10754 (0x023c ~ 0x2a02) while the usage
    boundary is specified as 0~10754 (0x00 ~ 0x2a02). This results in an
    incorrect interpretation of input reports, causing inputs to be ignored.
    By setting the Logical Minimum to zero, we align the logical boundary
    with the Usage ID boundary.

    Some notes:

    * There seem to be multiple variants of the VA104M keyboard. This
    patch specifically targets 04b4:07b1 variant.

    * The device works out-of-the-box on Windows platform with the generic
    consumer control device driver (hidserv.inf). This suggests that
    Windows either ignores the Logical Minimum/Logical Maximum or
    interprets the Usage ID assignment differently from the linux
    implementation; Maybe there are other devices out there that only
    works on Windows due to this problem?

  • f425458ea   HID: Use module_hid_driver macro ... Browse Code »

    Use the new module_hid_driver macro in all HID drivers that have
    a simple register/unregister init/exit.

    This also converts the hid drivers that test for a failure of
    hid_register_driver() and report the failure. Using module_hid_driver
    in those drivers removes the failure message.

  • 2f43f8749   HID: remove Paul Walmsley's copyright from places where it shouldn't be ... Browse Code »

    Paul Walmsley has implemented dynamic quirk handling back in 2007 through
    commits:

    2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c")
    8222fbe67c ("USB HID: clarify static quirk handling as squirks")
    8cef908235 ("USB HID: add support for dynamically-created quirks")
    876b9276b9 ("USB HID: add 'quirks' module parameter")

    and as such, his copyright rightly belongs to
    drivers/hid/usbhid/hid-quirks.c file.

    However when generic HID code has been converted to bus and individual
    quirks separated out to individual drivers on the bus, the copyright has
    been blindly transfered into all the tiny drivers, which actually don't
    contain any of Pauls' copyrighted code.

    Remove the copyright from those sub-drivers.

  • 4291ee305   HID: Add and use hid_<level>: dev_<level> equivalents ... Browse Code »

    Neaten current uses of dev_ by adding and using
    hid specific hid_ macros.

    Convert existing uses of dev_ uses to hid_.
    Convert hid-pidff printk uses to hid_.

    Remove err_hid and use hid_err instead.

    Add missing newlines to logging messages where necessary.
    Coalesce format strings.

    Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt

    Other miscellaneous changes:

    Add const struct hid_device * argument to hid-core functions
    extract() and implement() so hid_ can be used by them.
    Fix bad indentation in hid-core hid_input_field function
    that calls extract() function above.

  • 73e4008dd   HID: allow resizing and replacing report descriptors ... Browse Code »

    Update hid_driver's report_fixup prototype to allow changing report
    descriptor size and/or returning completely different report descriptor.
    Update existing usage accordingly.

    This is to give more freedom in descriptor fixup and to allow having a whole
    fixed descriptor in the code for the sake of readability.

  • afa5eb7c6   HID: remove compat stuff ... Browse Code »

    This removal was scheduled and there is no problem with later
    distros to adapt for the new bus, thanks to aliases.

    module-init-tools map files are deprecated nowadays, so that
    the patch which introduced hid ones into the m-i-t won't be
    accepted and hence there is no reason for leaving compat stuff in.
