The previously applied us-> host is passed to it as a parameter, and intf-> dev is also passed to it, this is used to register sysfs. As mentioned above, scsi_add_host () must be executed after scsi_host_alloc so that the SCSI core layer can know that such a host exists. If scsi_add_host () is successfu

Recently in the use of STM32 USB module to develop a project, it is very simple, the result of a fast two days to the USB packet buffer access to do a little summary here. The STM32 USB module packet buffer has 512B, but in the STM32 reference manual memory image shows that 0x40006000-0x400063ff, a whole lot of 512B, how can this, but also in the attempt to progr

However, if you don't care about the behavior in the USB core, it doesn't matter. Row 3 and row 3 do not pass data if you exit or break th

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. Line 3: If us_fw.x_disconnecting is set,
