Rome was not built in one day. Before making the USB flash drive work, we actually made a lot of preparations for the driver.
We continue to follow our feelings. storage_probe (), 972 to 975 rows, and a series of functions named init _ * are called at the moment. Here some lock mechanisms and wait mechanisms are involved, however, it is only initialization, but i
The following describes the usb_stor_control_thread () function. The wake-up command is the up ( amp; (us- gt; sema) from queuecommand, and the us- gt; 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.

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
password, anyone can log into the system, making it unsafe. You also need to be very careful when updating your software. Because if the Linux kernel is updated, bootloader is likely to be corrupted. This method is not flexible compared to a system installed on a hard disk. Because the kernel that bootloader needs to be booted is the same as the kernel version of the ISO image that is installed to boot.Fully installed to

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
