NAME

Since I disabled a audio device into the Audio devices Manager, I miss all my MIDI Input/Output devices in any DAW/Audio application, except Pro Tools 11. PT 11 shows one of my devices, but the other is still missing. What I did until now: Deinstalled / reinstalled my MOTU Micro lite and Fireface UFX drtivers. Deinstalled / reinstalled Ableton Live. Introduction to Human Interface Devices (HID); 2 minutes to read; b; D; E; In this article. Human Interface Devices (HID) is a device class definition to replace PS/2-style connectors with a generic USB driver to support HID devices such as keyboards, mice, game controllers, etc. Prior to HID, devices could only utilize strictly-defined protocols for mice and keyboards.

DESCRIPTION

evdev isan Xorg input driver for Linux´s generic eventdevices. It therefore supports all input devices that thekernel knows about, including most mice, keyboards, tabletsand touchscreens. evdev is the default driver on themajor Linux distributions.

Theevdev driver can serve as both a pointer and akeyboard input device. Multiple input devices are supportedby multiple instances of this driver, with one InputDevicesection of your xorg.conf for each input device that willuse this driver.

It isrecommended that evdev devices are configured throughthe InputClass directive (refer to xorg.conf(5))instead of manual per-device configuration. Devicesconfigured in the xorg.conf(5) are not hot-plug capable.

SUPPORTED HARDWARE

In general, anyinput device that the kernel has a driver for can beaccessed through the evdev driver. See the Linuxkernel documentation for a complete list.

CONFIGURATION DETAILS

Please refer toxorg.conf(5) for general configuration details and foroptions that can be used with all input drivers. Thissection only covers configuration details specific to thisdriver.

The followingdriver Options are supported:
Option 'ButtonMapping'string'

Sets the button mapping forthis device. The mapping is a space-separated list of buttonmappings that correspond in order to the physical buttons onthe device (i.e. the first number is the mapping for button1, etc.). The default mapping is '1 2 3 ... 32'. Amapping of 0 deactivates the button. Multiple buttons canhave the same mapping. For example, a left-handed mouse withdeactivated scroll-wheel would use a mapping of '3 2 10 0'. Invalid mappings are ignored and the defaultmapping is used. Buttons not specified in the user’smapping use the default mapping.

Option 'Device'string'

Specifies the device throughwhich the device can be accessed. This will generally be ofthe form '/dev/input/eventX', where X is someinteger. The mapping from device node to hardware issystem-dependent.

Option'DragLockButtons' 'L1 B2 L3B4'

Sets 'drag lockbuttons' that simulate holding a button down, so thatlow dexterity people do not have to hold a button down atthe same time they move a mouse cursor. Button numbers occurin pairs, with the lock button number occurring first,followed by the button number that is the target of the lockbutton. Property: 'Evdev Drag Lock Buttons'.

Option'DragLockButtons'M1'

Sets a 'master drag lockbutton' that acts as a 'Meta Key' indicatingthat the next button pressed is to be 'draglocked'. Property: 'Evdev Drag LockButtons'.

Option'Emulate3Buttons'boolean'

Enable/disable the emulation ofthe third (middle) mouse button for mice which only have twophysical buttons. The third button is emulated by pressingboth buttons simultaneously. Default: off. Property:'Evdev Middle Button Emulation'.

Option'Emulate3Timeout'integer'

Sets the timeout (inmilliseconds) that the driver waits before deciding if twobuttons where pressed 'simultaneously' when 3button emulation is enabled. Default: 50. Property:'Evdev Middle Button Timeout'.

Option'EmulateWheel'boolean'

Enable/disable'wheel' emulation. Wheel emulation means emulatingbutton press/release events when the mouse is moved while aspecific real button is pressed. Wheel button events(typically buttons 4 and 5) are usually used for scrolling.Wheel emulation is useful for getting wheel-like behaviourwith trackballs. It can also be useful for mice with 4 ormore buttons but no wheel. See the description of theEmulateWheelButton, EmulateWheelInertia,EmulateWheelTimeout, XAxisMapping, andYAxisMapping options. Default: off. Property'Evdev Wheel Emulation'.

Option'EmulateWheelButton'integer'

Specifies which button must beheld down to enable wheel emulation mode. While this buttonis down, X and/or Y pointer movement will generate buttonpress/release events as specified for theXAxisMapping and YAxisMapping settings. If thebutton is 0 and EmulateWheel is on, any motion of thedevice is converted into wheel events. Default: 4. Property:'Evdev Wheel Emulation Button'.

Option'EmulateWheelInertia'integer'

Specifies how far (in pixels)the pointer must move to generate button press/releaseevents in wheel emulation mode. Default: 10. Property:'Evdev Wheel Emulation Inertia'.

Option'EmulateWheelTimeout'integer'

Specifies the time inmilliseconds the EmulateWheelButton must be pressedbefore wheel emulation is started. If theEmulateWheelButton is released before this timeout,the original button press/release event is sent. Default:200. Property: 'Evdev Wheel EmulationTimeout'.

Option'GrabDevice'boolean'

Force a grab on the eventdevice. Doing so will ensure that no other driver caninitialise the same device and it will also stop the devicefrom sending events to /dev/kbd or /dev/input/mice. Eventsfrom this device will not be sent to virtual devices (e.g.rfkill or the Macintosh mouse button emulation). Default:disabled.

Option 'InvertX'Bool'
Option 'InvertY'Bool'

Invert the given axis. Default:off. Property: 'Evdev Axis Inversion'.

Option'IgnoreRelativeAxes'Bool'
Option 'IgnoreAbsoluteAxes'Bool'

Ignore the specified type ofaxis. Default: unset. The X server cannot deal with devicesthat have both relative and absolute axes. Evdev tries toguess wich axes to ignore given the device type and disablesabsolute axes for mice and relative axes for tablets,touchscreens and touchpad. These options allow to forciblydisable an axis type. Mouse wheel axes are exempt and willwork even if relative axes are ignored. No property, thisconfiguration must be set in the configuration.
If either option is set to False, the driver will not ignorethe specified axes regardless of the presence of other axes.This may trigger buggy behavior and events from this axisare always forwarded. Users are discouraged from settingthis option.

Option'Calibration' 'min-x max-x min-ymax-y'

Calibrates the X and Y axes fordevices that need to scale to a different coordinate systemthan reported to the X server. This feature is required fordevices that need to scale to a different coordinate systemthan originally reported by the kernel (e.g. touchscreens).The scaling to the custom coordinate system is donein-driver and the X server is unaware of the transformation.Property: 'Evdev Axis Calibration'.

Option 'Mode'Relative'|'Absolute'

Sets the mode of the device ifdevice has absolute axes. The default value for touchpads isrelative, for other absolute. This option has no effect ondevices without absolute axes.

Option 'SwapAxes'Bool'

Swap x/y axes. Default: off.Property: 'Evdev Axes Swap'.

Option'XAxisMapping' 'N1N2'

Specifies which buttons aremapped to motion in the X direction in wheel emulation mode.Button number N1 is mapped to the negative X axismotion and button number N2 is mapped to the positiveX axis motion. Default: no mapping. Property: 'EvdevWheel Emulation Axes'.

Drivers Aim_srl Input Devices Input

Option'YAxisMapping' 'N1N2'

Specifies which buttons aremapped to motion in the Y direction in wheel emulation mode.Button number N1 is mapped to the negative Y axismotion and button number N2 is mapped to the positiveY axis motion. Default: '4 5'. Property:'Evdev Wheel Emulation Axes'.
