Mouse in OpenWrt
Now let’s connect the input-device: a mouse.
The connecting procedure is the same as of the keyboard connecting. Therefore on the stage of configuration OpenWrt the following modules are to be selected:
Base system:
<*> busybox:
Linux System Utilities:
<*> lsusb
Kernel modules:
USB Support:
<M> kmod-usb-hid
Let’s connect a mouse and check the output dmesg:
|
root@OpenWrt:/# dmesg |
A new device has to be created in the directory /dev:
|
root@OpenWrt:/# ls /dev/input/ -l crw-r--r-- 1 root root 13, 64 Jan 1 00:01 event0 |
My output lsusb looks like this:
|
root@OpenWrt:/# lsusb Bus 001 Device 001: ID 1d6b:0001 Bus 002 Device 001: ID 1d6b:0002 Bus 001 Device 002: ID 0a05:7211 Bus 001 Device 003: ID 0951:1603 Bus 001 Device 004: ID 15ca:00c3 |
The device with ID 15ca:00c3 Textech International Ltd. Mini Optical Mouse is the mouse.
Let’s check the existence of the device’s file in the directory /proc:
|
root@OpenWrt:/# cat /proc/bus/input/devices I: Bus=0003 Vendor=15ca Product=00c3 Version=0110 N: Name="USB Optical Mouse" P: Phys=usb-ssb0:1-1/input0 S: Sysfs=/devices/ssb0:1/usb1/1-1/1-1:1.0/input/input0 U: Uniq= H: Handlers=event0 B: EV=17 B: KEY=70000 0 0 0 0 0 0 0 0 B: REL=103 B: MSC=10 |
Let’s check the response to a mouse movement:
