HID: logitech: add HID++ support for Logitech MX Anywhere 3S

2026-01-08T11:22:01+00:00

I've acquired a Logitech MX Anywhere 3S mouse, which supports HID++ over
Bluetooth. Adding its PID 0xb037 to the allowlist enables the additional
features, such as high-resolution scrolling. Tested working across multiple
machines, with a mix of Intel and Mediatek Bluetooth chips.

HID: Elecom: Add support for ELECOM M-XT3DRBK (018C)

2026-01-07T22:36:58+00:00

Wireless/new version of the Elecom trackball mouse M-XT3DRBK has a
product id that differs from the existing M-XT3DRBK.
The report descriptor format also seems to have changed and matches
other (newer?) models instead (except for six buttons instead of eight).
This patch follows the same format as the patch for the M-XT3URBK (018F)
by Naoki Ueki (Nov 3rd 2025) to enable the sixth mouse button.

HID: quirks: work around VID/PID conflict for appledisplay

2026-01-07T22:36:58+00:00

For years I wondered why the Apple Cinema Display driver would not
just work for me. Turns out the hidraw driver instantly takes it
over. Fix by adding appledisplay VID/PIDs to hid_have_special_driver.

HID: Apply quirk HID_QUIRK_ALWAYS_POLL to Edifier QR30 (2d99:a101)

2026-01-07T22:36:58+00:00

The USB speaker has a bug that causes it to reboot when changing the
brightness using the physical knob.

Add a new vendor and product ID entry in hid-ids.h, and register
the corresponding device in hid-quirks.c with the required quirk.

HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()

2026-01-07T17:35:58+00:00

`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data
into `ihid->rawbuf`.

The former can come from the userspace in the hidraw driver and is only
bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set
`max_buffer_size` field of `struct hid_ll_driver` which we do not).

The latter has size determined at runtime by the maximum size of
different report types you could receive on any particular device and
can be a much smaller value.

Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`.

The impact is low since access to hidraw devices requires root.

HID: quirks: Add another Chicony HP 5MP Cameras to hid_ignore_list

2026-01-07T14:20:51+00:00

Another Chicony Electronics HP 5MP Camera with USB ID 04F2:B882
reports a HID sensor interface that is not actually implemented.

Add the device to the HID ignore list so the bogus sensor is never
exposed to userspace. Then the system won't hang when runtime PM
tries to wake the unresponsive device.
