This report is used for Consumer Control buttons, which can be mapped using the provided Windows only software. Here is an excerpt from the original descriptor: INPUT(2)[INPUT] Field(0) Flags( Constant Variable Absolute ) Field(1) Flags( Constant Variable Absolute ) Field(2) Flags( Constant Variable Absolute ) The issue is the Constant flag specified on all 3 fields, which causes the hid driver to ignore changes in these fields and essentialy causes the buttons to not work at all. The submitted driver patches the descriptor to end up with the following: INPUT(2)[INPUT] Field(0) Flags( Variable Relative ) Field(1) Flags( Variable Relative ) Field(2) Flags( Variable Relative ) The Constant bit is reset and the Relative bit has been set in order to prevent repeat events when holding down the button. Additionally, the device name is changed from the hardware-reported "SINOWEALTH Wired Gaming Mouse" to "Glorious Model O" or "Glorious Model D".

The first thing the hid-lg-g15 driver does is disable this behavior. We have received a bugreport that this does not work when the keyboard is connected through an Aten KVM switch. Using a gaming keyboard with a KVM is a bit weird setup, but still we can try to fail a bit more gracefully here. On the G510 keyboards the same USB-interface which is used for the gaming keys is also used for the media-keys. Before this commit we would call hid_hw_stop() on failure to disable the F# emulation and then exit the probe method with an error code. This not only causes us to not handle the gaming-keys, but this also breaks the media keys which is a regression compared to the situation when these keyboards where handled by the generic hidinput driver. This commit changes the error handling to clear the hiddev drvdata (to disable our .raw_event handler) and then returning from the probe method with success. The net result of this is that, when connected through a KVM, things work as well as they did before the hid-lg-g15 driver was introduced.

Note: With commit 8ec321e96e05 ("HID: Fix slab-out-of-bounds read in hid_field_extract") I no longer hit the kernel Oops as we instead fail "controlled" at probe if there is a report too long in the HID report-descriptor. hid_report_raw_event() is an exported symbol, so presumabely we cannot always rely on this being the case.

| * | HID: ite: Only bind to keyboard USB interface on Acer SW5-012 keyboard dockHans de Goede2020-02-031-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8f18eca9ebc5 ("HID: ite: Add USB id match for Acer SW5-012 keyboard dock") added the USB id for the Acer SW5-012's keyboard dock to the hid-ite driver to fix the rfkill driver not working. Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the "Wireless Radio Control" bits which need the special hid-ite driver on the second USB interface (the mouse interface) and their touchpad only supports mouse emulation, so using generic hid-input handling for anything but the "Wireless Radio Control" bits is fine. On these devices we simply bind to all USB interfaces. But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10 (SW5-012)'s touchpad not only does mouse emulation it also supports HID-multitouch and all the keys including the "Wireless Radio Control" bits have been moved to the first USB interface (the keyboard intf). So we need hid-ite to handle the first (keyboard) USB interface and have it NOT bind to the second (mouse) USB interface so that that can be handled by hid-multitouch.c and we get proper multi-touch support. This commit changes the hid_device_id for the SW5-012 keyboard dock to only match on hid devices from the HID_GROUP_GENERIC group, this way hid-ite will not bind the the mouse/multi-touch interface which has HID_GROUP_MULTITOUCH_WIN_8 as group. This fixes the regression to mouse-emulation mode introduced by adding the keyboard dock USB id.

Previously we were ignoring extPower, which resulted in wrong values. Example: With an unplugged mouse $ cat /sys/class/power_supply/hidpp_battery_0/status Charging This patch fixes that, it also renames charge_sts to flags as charge_sts can be confused with chargeStatus from the spec.

When the device is brought up and we try to query the battery, figure out if it supports the old or the new feature. If it supports the new feature, record the feature index and read the battery voltage and its charge status. The device will respond with three bytes: the first two are its voltage, and the last one is a bitset, reporting if the battery is charging, fast or slow, in critical level or discharging. If everything went correctly, record the fact that we're capable of querying battery voltage. Note that the protocol only gives us the current voltage in mV. We store that as-is, but when queried, we report it in uV as expected by sysfs. Like we do for other ways of interacting with the battery for other devices, refresh the battery status and notify the power supply subsystem of the changes in voltage and status. Since there are no known devices which implement both the old and the new battery feature, we make sure to try the newer feature first and only fall back to the old one if that fails.
