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.

who was involved in developing the USB subsystem in the Linux Kernel told me that a LUN is a driver in the device. The following is an example of the purpose of introducing LUN in USB. Some card readers can have multiple slots, such as two, one supporting the CF card and the other supporting the SD card. In this case, distinguish the devices in these two slots,

compilation switches related to a variety of specific products. They have some defined transmission functions, while others share common functions. Row 3: judge us-> flags. Remember the flags we mentioned when talking about the unusual_devs.h file. It was used for the first time. Some devices have set the flag us_fl_single_lun, indicating that it only has one Lun. There are a lot of devices like this, just grab one from unusual_devs.h: 596 unusual_dev (0x054c, 0x002d, 0x0100, 0x0100, 597 "Sony

Some companies' products have to be delayed by 989 μs in the command and data phases, at first, we found that Genesys logic's products had this problem, and later we found that more products had the same problem. Therefore, the flag us_fl_go_slow is used. If you are interested in looking at the early Linux kernel, you will find that there was actually no such flag. At that time, a usb_vendor_id_genesys is defined, directly compar

How do I use a USB port storage device in a Linux environment? This is a large number of computer forums appear more than a problem, with this can be seen in many computer players in front of a problem.
