从进入usb_serial_probe()开始,usb-serial驱动才真正进入到驱动内部。 一、usb_serial_probe()---接口与驱动的精确匹配 1、查找匹配的驱动,此时匹配的驱动就是pl2303。 type=search_serial_device(interface); // 遍历usb_serial_driver_list链表,搜索与该interface匹配的驱动,此时type为drv 2、创建一个usb_serial...
Linux 设备模型中三个很重要的概念就是总线,设备,驱动.即bus,device,driver,而实际上内核中也定义了这么一些数据结构,他们是struct bus_type,struct device,struct device_driver,这三个重要的数据结构都来自一个地方,include/linux/device.h.我们知道总线有很多种,pci总 线,scsi总线,usb总线,所以我们会看到Linux内...
The universal serial bus (USB) bus driver connects a USB hub to a Windows Embedded Compact device. Windows Embedded Compact loads this driver if the peripheral device interconnect (PCI) bus enumerator detects a USB hub. You use the USB bus driver when you want to support connecting your Windo...
