In the "USB series three", we implemented a series of SCSI commands, in this series, we want to implement the command to write sector to the U disk, so this article is relatively easy, more is to give a realization of the source program.In the third USB series, the SCSI commands we implement are: INQUIRY, read capacity (10), TEST UNIT ready, REQUEST sense, read (

Use a USB flash drive to install CentOS and write the boot on the USB flash drive. I found that I am a genius! Let's review the scenario: there is an old machine in the company. My colleague said it was okay to study how to install a Linux. I just downloaded a CentOS6.4 a few days ago, and I just completed the work. Unfortunately, the broken machine does not have

How to add write protection and Remove write protection for the USB flash drive in the Win10 System If your USB flash drive (or mobile hard drive) Stores important information and is not rewritten by others, you can set the USB flash drive to "

device type or block device type, for example, the mouse is a character device and the hard disk is a block device, after successful registration, the system will report a master configuration.The primary device ID is the unique identifier of the system. The driver creates a device file typically stored in the/dev directory based on the master device number. When we want to access this hardware, we canFiles are executed using open, read, write, close

Linux dd command to test the read/write speed of the USB flash drive and the dd read/write speed 1. Brief description of the dd command: If = input file, of = output file, ibs = number of bytes read at a time, obs = number of bytes written at a time, bs = set the number of bytes read and write at a time, skip = numbe

Recently, a lot of users asked why the U disk will be written to protect the U disk write protection to do, how should it be lifted? U disk write protection, the files on the U disk can only be read can not be deleted, can be modified but not saved, although the virus is very effective, but also to the user has brought trouble. How to solve the

[Blog.csdn.net/lanmanck] Once upon a while, we found a job as a driver engineer, with a low monthly salary. The Code of people we have never touched cannot be understood at all. Today is good. If we do not want to pursue differentiation, we can allow the system to communicate with USB devices without drivers. Linux will not talk about it. libusb is very useful. Now we will talk about windows. Winusb is a kind of middleware similar to libusb and

HoweverIdeaAnd this hardware is really attractive.Greg HughesI have discussed how to write better programs for this small button many times, but it has not been put into practice yet. Bryan Batchelder is also interested in this and thanks for his attempt for all of us.Back to Top Interaction and abstraction with

USB flash drives are also widely used and are also an important device for storage. USB flash drives are written for protection when they are plugged in to the computer. At this time, USB flash drives cannot be used for related operations. The following describes how to crack the USB flash drive

Use the DD command in Linux to test the read/write speed of USB and SSD hard disks.Disk Drive Speed The disk drive speed is measured by the amount of read/write data per unit of time. The DD command is a simple command line tool that can read and write any data block on the disk and measure the read/
