2025-08-23hkbd: remove erorr detection in KDSKBSTATE ioctlShengYi Hung
The KDSKBSTATE ioctl brings the LED up. However, some keyboards (like qemu keyboard) may not have LED or failed to set the LED due to unexpected reason. Therefore, removing the error check as ukbd(4) does allow the keyboard works correctly with kbdcontrol(4). Also move hw.hid.hkbd.no_leds sysctl out of HID_BUG thus users can disable setting LEDs PR: 288968 Reviewed by: wulf Tested by: trashcan@ellael.org, marklmi26-fbsd@yahoo.com, trkellers@gmail.coom Approved by: lwsu (mentor), markj (mentor) MFC after 1 week Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D52101 mvalsmva
2025-08-18u2f(4): a HID driver for FIDO/U2F security keysVladimir Kondratyev
While FIDO/U2F keys were already supported by the generic uhid(4) and hidraw(4) drivers, this driver adds some additional features an does steps to tighten the security of FIDO/U2F access. - It automatically loads through devd. - Automatically enables HQ_NO_READAHEAD for FIDO/U2F devices. - Implements only miminum set of features. - Do not requires external devfs configuration to set character device permissions. - Names character device as u2f/# to make possible capsicum or any other pledge()-style sandboxing.

2025-08-18hid: Add HQ_NO_READAHEAD quirk and implement it in usbhid(4)Vladimir Kondratyev
It disables interrupt emulation on poll-driven buses like USB and forces aquiring of only one USB frame per read(2) operation. This avoids an FIDO/U2F issue where IN endpoint data received from the device right before the file handle is closed, gets lost.

2025-04-27hidraw(4): Add additional hidraw input/output report ioctlsVladimir Kondratyev
to Linux hidraw compatibility API. Respective Linux commit f43d3870cafa made by Dean Camera message is: Currently the hidraw module can only read and write feature HID reports on demand, via dedicated ioctls. Input reports are read from the device through the read() interface, while output reports are written through the write interface(). This is insufficient; it is desirable in many situations to be able to read and write input and output reports through the control interface to cover additional scenarios: - Reading an input report by its report ID, to get initial state - Writing an input report, to set initial input state in the device - Reading an output report by its report ID, to obtain current state - Writing an output report by its report ID, out of band This patch adds these missing ioctl requests to read and write the remaining HID report types. Note that not all HID backends will neccesarily support this (e.g. while the USB link layer supports setting Input reports, others may not). FreeBSD native uhid(4) compatible API already has similar ioctls. MFC after: 3 days

2024-11-26hms(4): improve scroll with IICHID_SAMPLINGEdward Tomasz Napierala
The current quirk is designed to discard duplicated data read from the chip. Problem is, it also discards real events when they happen to be identical, which is the case with scroll wheel events; differently from X/Y they always move by fixed offset. This results in two-finger scroll that would stop mid-way that could be fixed by manually setting dev.hms.0.drift_thresh to 0. To fix that, don't discard duplicates when there's wheel movement. For users with actual duplicates problem this will result in scroll suddenly becoming quite inertial, but it will stop moving at any touch, so shouldn't be terrible.
