HID: elecom: rewrite report fixup for EX-G and future mice

2018-01-23T14:39:54Z

This patch rewrites the mouse report fixup used for the DEFT and HUGE elecom trackballs in order to make it generic enough to fix other elecom mice with similar issues. This patch also uses this new report fixup function to fix the Elecom EX-G trackball which has 6 physical buttons and a similar issue to the other two mice. Elecom's track record has so far shown that they like to re-use the same report descriptor for multiple different mice regardless of the number of buttons the mouse has. This means that the missing buttons on multiple mice can be fixed in one function without introducing phantom buttons which would in turn cause the number of mouse buttons to be misreported to userspace. This patch drops the very verbose report descriptor "diff" comment for a more abridged yet hopefully just as informative generic version. Signed-off-by: Tomasz Kramkowski Signed-off-by: Jiri Kosina

HID: hid-elecom: extend to fix descriptor for HUGE trackball

2017-10-11T13:46:22Z

In addition to DEFT, Elecom introduced a larger trackball called HUGE, in both wired (M-HT1URBK) and wireless (M-HT1DRBK) versions. It has the same buttons and behavior as the DEFT. This patch adds the two relevant USB IDs to enable operation of the three Fn buttons on the top of the device. Cc: Diego Elio Petteno Signed-off-by: Alex Manoussakis Signed-off-by: Jiri Kosina

HID: elecom: extend to fix the descriptor for DEFT trackballs

2017-05-11T08:49:14Z

The ELECOM DEFT trackballs report only five buttons, when the device actually has 8. Change the descriptor so that the HID driver can see all of them. For completeness and future reference, I included a side-by-side diff of the part of the descriptor that is being edited.

HID: Use module_hid_driver macro

2013-01-03T09:27:31Z

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.

HID: Add and use hid_: dev_ equivalents

2010-12-10T14:10:38Z

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. Signed-off-by: Joe Perches Signed-off-by: Jiri Kosina

HID: allow resizing and replacing report descriptors

2010-08-09T17:52:42Z

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. Signed-off-by: Nikolai Kondrashov Signed-off-by: Jiri Kosina
