can write bare devices instead of windows. That is to say, if the USB flash disk is not partitioned in windows (which cannot be written in windows at this time), it can still be written in linux.
At of =/dev/sdb, it was written from the starting position of the USB flash disk. The result was simulated as a
We followed storage_probe () almost completely, and it seems that everything is about to end, but do you think you haven't understood how the device works so far? USB flash drives are not only USB devices but also "disks". They also need to comply with the USB Mass Storage protocol and Transparent SCSI specifications.

So here, we need to carefully check the path we have chosen. Obviously, we have already said that for a USB flash drive, spec specifies that it belongs to the bulk-only transmission mode, that is, its US-> protocol is us_pr_bulk. This is just determined in get_device_info. Theref
introduce it later.
Our story is based on the drivers/usb/storage directory. In fact, the code here clearly shows how the USB flash drive we frequently access is working and how it is driven. But the code in this directory does not live in a paradise. They are always closely related to the outside world. You can cont
For a USB-enabled motherboard to be installed on a USB flash drive, you must first prepare a hard drive with a system installed to complete the following steps.

Solve the "Deviceisbusy"-Linux general technology-Linux technology and application information that appears when you attach a USB flash drive or a mobile hard drive in Linux. The following is a detailed description. When you mount a USB
The following describes the usb_stor_control_thread () function. What wakes up is the up ( (us-> sema) from the queuecommand, and us-> sulfate is assigned to the Server Load balancer, in contrast, the Server Load balancer is a parameter passed in when the SCSI core layer calls the queuecommand. Focus on usb_stor_control_thread (). Row 3: As mentioned earlier, we have to look at the dev_mutex lock from a higher perspective after reading the entire module.

Get what we need from the two tables, and then the following code is expanded around the two pointers. (Unusual_dev and id) continue to read get_device_info ().
Row 3: Record unusual_dev in us. There is also such a member in us. In this way, it will be easy to use after recording. Because us runs through the whole story, it is very convenient to access its members and can be accessed at any time, however, the us_unusual_dev_list and storage_usb_ids tables will not be reused this time. Because w
Synchronizing data to a mobile hard disk or USB flash drive is especially suitable for the situation where the unit and home have computers, and it can be used for secure data backup.

In the XP system, if you insert a mobile device, such as a USB flash drive or a mobile hard disk, the system will automatically search for media files and play back the files. If you want to disable the automatic playback function of Windows XP at one time, follow these steps:
1. Click Start> Run. In the open box, type gpedit. MSC and click OK to open the Group
I have always recommended using group policies to disable automatic playback. Today, I saw a question post in the forum. This post attempts to describe a point of view-to avoid double-clicking or inserting a USB flash drive (mobile hard drive) poisoning, the Group Policy Editor alone is invalid. You need to modify the

Now that you know how to write the module, writing the device driver is naturally not difficult. I believe that no one who writes a module will find it difficult to write a device driver. Really, I'm not telling you the truth. writing a driver is not difficult. you can say with confidence that you can already write a device drive... Info nbsp
