How can I reinstall Windows 7 with a USB flash drive ?, USB flash drive win7 reinstallation
If you do not have an optical drive or a CD, you can create a USB flash drive to quickly install the Windows 7 operating system. Next, let's take a look at how to install Win7 with a USB flash drive.

USB flash drive installation system tutorial, USB flash drive tutorial
At present, USB flash drives are very useful and can be used to install the system on a computer. How can I install the system on a computer?
Create a u disk as a u-depth boot disk, restart the computer, wait for the boot screen to press the boot shortcut key, select the u disk to start to
the drive to restart the virtual machine. Then shut down the machine.The physical machine Ubuntu also restarts.Open the VirtualBox again, start the virtual machine, and insert the USB drive. Will find the lower right corner of the USB settings can be recognized, check the USB drive device. or select "Device" from the menu barAfter selection, it can be recognized

Now the U-disk is an important part of our life, can store a lot of information, it is very convenient to carry. The "technology" of the desktop computer drive also has a certain proportion of the market. Desktop USB has many advantages, such as the ability to provide data protection and anti-virus software, etc., has a high cost-effective. However, after the USB flash drive system, you may encounter the pr
During the project development, we need a USB-to-relay device to control the wireless transmitter device when the switch is enabled. When purchasing the device, the sourcing department buys a batch of devices without knowing the operating environment of the relay device, later, we found that the device manufacturer only provides the Windows library, and we want to develop it in Linux. Speechless ......
Although the relay device has no drive, I don't k
phase. This phase is optional. If the wvalue And Windex data we transmit cannot accommodate, or the information needs to be read from the device, it needs to be carried out through the data phase, the data phase is implemented through the ep0buf, ep0bch, and ep0bcl registers. The data phase can transmit 64 bytes of data at a time.
This phase is often used incorrectly, especially when data is transmitted from the upper computer to the lower computer, which leads to a strange phenomenon: the cor

The USB keyboard is not available, the computer is not detected after inserting the keyboard, and the exclamation mark device is not present.
Reason analysis:
Look at the human body. There are two devices in the input device, and the hardware ID confirms that the USB input device is the mouse and the English device is actually the keyboard. That is, the Windows system incorrectly identifies the key
Cause: it is suspected that during initialization, it takes time to read the USB flash disk information. Therefore, the code for reading the USB flash disk information is moved to domodal (), so that it can be properly displayed on the USB flash disk.

installing CentOS is the choice of USB flash drive, Linux text mode, using the installation method will cause the Grub boot menu installed to the USB stick (no way to avoid), the installation process is omitted. Workaround:1. After booting into the system using the U-disk:#grubGrub>find/grub/stage1(hd0,0)Grub>reboot2. Modify the system grub.conf and MENU.LST configuration:Splashimage= (hd0,0)/grub/splash.xp
other half. On the contrary, whenever one structdevice_driver is born, it goes to the devices linked list of the bus to find its devices. If appropriate, call device_bind_driver to bind the device. If it cannot be found, it does not matter. wait.
In fact, perfecting this triangular relationship is one of the important missions completed in each device driver initialization phase. Let's go back to the code. the usb_register function is called, but what is the parameter passed to it?

Yun-Habitat community small tip you, if you do not need to use like a mobile phone helper to install software or download software we do not need to turn on the USB mode, this USB debugging mode is the developer option OH.
1. Open the Samsung S5USB Debug mode is very simple, we click on the phone "application."
2. Find "Set" here click on it (because we want to find the phone version).
