User-space I/O driver support for HID subsystem

Linux 3.6～

メモ

  • HIDのトランスポートレイヤを実装するためのドライバ。
  • this driver allows to write the transport-layer driver in user-space like USB-HID and Bluetooth-HID do in kernel-space.
  • The UHID driver is a"low-level/transport-level driver (hid_ll_driver)" which was written to allow user-space to act as I/O drivers for the HID subsystem.

関連の仕組み

↑

hidraw

  • UHID cannot be used to parse HID-reports in user-space and write special HID-drivers. You should use hidraw for that.
↑

uinput

  • User level driver support for input subsystem
  • It does not do any sophisticated protocol parsing or similar but simply forwards the events to all interested listeners.

使い方

  • User-space can simply open /dev/uhid and create/destroy hid-devices in the hid-core.
  • Each open file-descriptor on /dev/uhid can control exactly one device.
  • The UHID driver registers the new device with the HID core and user-space can now transmit I/O data to the kernel
