the kick_khubd function, add the current hub to the Hub driver queue hub_event_list, and then wake up the hub daemon wake_up (khubd_wait) to start parsing what happened to the hub. 3. After hub_thread is awakened, It will be executed and hub_events will also be executed. 4.

Execute PS-A | grep khubd on the terminal, and the khubd process is displayed. This is the hub daemon process. Our device is inserted into the USB interface (whether it is inserted with the hub, after the sub-hub), the daemon detects the issue and then notifies the master controller of the interruption. The master cont

Objective: To study USB in depth and take notes here. Welcome to the discussion. [Linux 3.2] [Driver/USB/CORE/hub. C] Function: usb_hub_init int usb_hub_init(void){if (usb_register(hub_driver) Usb_hub_init mainly implements two functions: one is to register the hub

development.Windows driver according to the kind to divide, roughly divides into the bus drive, the function drive, the filter drives three kinds.USB is a hardware interface and must be disconnected from the lowest-level bus driver.The bus driver is responsible for managing all devices connected to a certain type of bus, such as a USB bus,It is responsible for m

After using the hub on ce, pay attention to the following points for the USB driver:1. Make sure that the buffer for transmission is large enough.2. If the USB sleep mode is set, make sure that the sleep mode is enabled during sleep.Modify the buffer:E: \ WINCE600 \ PLATFORM \ SMDK6410 \ src \ drivers \

The system also told me that there is no administrator rights, oh My computer I do not have administrative rights ... I am also drunk, and then I Baidu has an administrator authorized registry, finally have permission, so I decisively kicked it to the garbage box. As for the blue screen, OK, blue screens and that folder is not closed, because the cause of the blue screen I do not know why, so just s

Do countless years of computer engineers, incredibly today USB problems, it took me one hours to solve. The problem is that the system is used, the USB mouse is gone, then the system blue screen, see is dump RAM. I was too lazy to wait and restarted the system. Then, after the system restarts, the mouse is lost. I can't find it anymore. Helpless, find PS2 mouse, point to open Device Manager, incredibly

recently, users of the Win7 system have found that when the machine is turned on, the bottom right corner of the desktop will jump out of the USB root hub prompt. Sometimes it even pops up Microsoft USB 2.0 host controller simulator has been safely removed, and if you open Device Manager you will find the Microsoft USB
