From the Protocol to the Protocol (above) In structusb_driver, the prototype of. Probe and. Disconnect is as follows: 836 int (* probe) (struct usb_interface * INTF, 837 const struct usb_device_id * ID ); 838 839 void (* disconnect) (struct usb_interface * INTF ); Let's take a look at the parameter structusb_device_id, Which is needless to say. As we have already introduced, where does struct usb_interface come from? Let's start with struct usb_device. We know that each device corresponds to a s

1, after the system plugged into the USB device, from the console interface has the following prompt:From the console information, you can see the inserted USB device name.As you can see, the plugged-in USB device is sde4.However, if the CRT tool is remotely connected to the past, you can use the following command to view the

In the code of the entire USB-storage module, the most soul part is in a function called usb_stor_control_thread (), which is naturally the climax of our entire story. Some special functions are called from the usb_stor_acquire_resources () function, which we will see soon. It only appears once in the whole play, that is, in storage_probe, where the row number is 1005. However, before that, there were four functions in front of us, namely get_device_i

Booting from the USB stick there are three ways: USB-HDD, Usb-cdrom, USB-FDD, which USB-FDD format is older, at the same time there is a certain problem of compatibility, and currently only for USB-HDD and

In the previous article, we have given the link address of the USB protocol, from this article, we will involve a lot of USB 1.1 content, our guiding ideology is to start with the familiar USB 1.1 protocol, first use off-the-shelf HCD and USBD, directly face the client driver programming, see the results as soon as possible, So that readers have confidence in the

Technorati label: Boot Disk How to Create a USB flash drive and install the system with a USB flash drive (reprinted) Many of my friends are using laptops without optical drives, but the problem also arises. When we need to reinstall the system, there is no optical drive. What should we do? Maybe you can say that the hard disk can be installed under DOS, but how many people will use dos? In fact, not only d

Someone asked, how can I write a driver for so long? Indeed, it is not easy for everyone to go all the way, but now that we have reached today, we can only stick to it.

Linux-USB Gadget OverviewThe Linux-USB Gadget driver framework (hereinafter referred to as gadget) provides software functions for devices defined by the USB protocol.Compared with the Linux USB host driver, the gadget driver appears later than 2.4.23.The Gadget Framework proposes a set of standard APIs, which are driv

For the entire USB-storage module, the usb_stor_init () function is its start. However, for the USB flash drive, the function that actually drives the USB flash drive starts with the storage_probe () function. As long as the two parallel lines overlap, it is doomed to start a lifetime of entanglement, no matter whether the middle is a short separation.
