关于Input设备，说明：
（1）ls -l /dev/input，得到设备名称和属性，注意此处没有input号这种Input层分配的内容，以event为主。如：
# ls -l /dev/input
crw-rw---- root input 13, 66 1970-01-01 00:00 event2
crw-rw---- root input 13, 33 1970-01-01 00:00 mouse1
crwxrwxrwx root input 13, 65 1970-01-01 00:00 event1
crw-rw---- root input 13, 32 1970-01-01 00:00 mouse0
crw-rw---- root input 13, 64 1970-01-01 00:00 event0
crw-rw---- root input 13, 63 1970-01-01 00:00 mice
如果这么些设备中无法确认哪个是目前在用的设备？可以采用这种方式：cat他们，然后操作鼠标或者键盘，哪个输出乱码就是用的哪个。
（2）cat /proc/bus/input/devices，主要信息是：
N: Name="s3c-keypad-rev0000"
P: Phys=s3c-keypad/input0
S: Sysfs=/class/input/input0
H: Handlers=kbd event0
N: Name="S3C TouchScreen"
P: Phys=input(ts)
S: Sysfs=/class/input/input1
U: Uniq=
H: Handlers=kbd mouse0 event1
N: Name="ADXL34x accelerometer"
P: Phys=1-0053/input0
S: Sysfs=/class/input/input2
U: Uniq=
H: Handlers=mouse1 event2
分配的Input节点全在Sysfs上，真正的设备dev在Handlers上。
（3）ls -l /sys/class/input，类设备信息：
drwxr-xr-x root root 1970-01-01 00:00 mice
drwxr-xr-x root root 1970-01-01 00:00 input0
lrwxrwxrwx root root 1970-01-01 00:04 event0 -> input0/event0
drwxr-xr-x root root 1970-01-01 00:00 input1
lrwxrwxrwx root root 1970-01-01 00:04 mouse0 -> input1/mouse0
