这样驱动就会根据自己的类型(字符设备类型或块设备类型,例如鼠标就是字符设备而硬盘就是块设备)向系统注册,注册成功系统会反馈一个主设备号,这个主设备号就是系统对它的唯一标识(例如硬盘块设备在/proc/devices中显示的主设备号为3 ,我们用ls -l /dev/had看到的主设备就肯定是3)。驱动就是根据此主设备号来创建...
/sys/devices/pci0000:00/0000:00:12.2/usb1/1-5/1-5.4/idVendor也就是符号链接:/sys/bus/usb/devices/1-5.4/idVendor 为了勒脚对于一个设备来讲哪些属性是可以访问的,可以查看设备的目录下有哪些文件存在,如在/sys/bus/usb/devices/1-5.4/ 目录下有: 1-5.4:1.0 bDeviceSubClass configuration idProduct ...
挂载点规则: 根据设备节点名称和usb的PID命名的。比如:存在/dev/sdc4设备节点,并且此节点的的USB的PID为1234,那么会自动在/tmp/udisk/下面创建,sdc4_1234挂载点,并将/dev/sdc4挂载到/tmp/udisk/sdc4_1234 int udisk_scan_mount(void) { int ret = 0; struct udev *udev; struct udev_device *device;...
