HID input manager for keyboards and mice
devi-hid [general_opts] protocol* [protocol_opts]* filter* [filter_opts]*
Any supported platform that has io-hid running.
- -g input_group
- Input group (default: 1).
- List the internal modules. Modules are listed in the following format
where class may be P (protocol) or F (filter):
module name | date last compiled | revision | class
- Start the resource manager interface.
- Verbose output. More v characters cause more verbosity.
The protocol modules and their options are:
kbd — keyboard scan codes (connected to primary keyboard)
- -k rate[,delay]
- Keyboard rate (Hz),delay (ms). If you continually depress a key, after delay milliseconds, it will input data rate times a second. The default is 150Hz after 500ms.
- -u device
- Optional, USB device number.
- mouse — common mouse protocol (no options)
The filter modules and their options are:
keyboard — translate scan codes to UNICODE
- -k kbd_file
- The file to use to map the keyboard to support international languages or alternate layouts, such as Dvorak.
rel — filters and compresses relative coordinates of mouse events
- Wheel acceleration parameter (default 10); the higher this value, the faster the mouse wheel acceleration.
- -G gain
- Motion multiplier (default 1).
- Swap right and left buttons.
- -T threshold
- Speed-doubling threshold in mickeys/second. If the mouse speed exceeds this threshold, the cursor will move twice as far as it normally does per mickey. (A mickey is the smallest amount of motion the mouse can detect.) The default threshold is 100.
- Reverse X.
- Reverse Y.
This manager is a universal input daemon for keyboards and mice. It is a client of io-hid, the HID server.
This manager doesn't need information about the physical interfaces of real devices: it relies on service from the io-hid resource manager and supplementary input modules.
If you specify the verbosity option, activity messages are sent to the console screen and to the system log.
Typical command line to start the keyboard and mouse manager:
devi-hid kbd mouse
- Used by devi-hid
If an error occurs in starting devi-hid, the keyboard or mouse will not work. If you specify at least one v option, activity details will be reported on the console screen and will be appended to the system log; for more detail, increase the verbosity level.
