Remember this mount point, which varies according to the Linux system. Step 2: mount the USB

From the Protocol to the Protocol (above) In structusb_driver, the prototype of. Probe and. Disconnect is as follows: 836 int (* probe) (struct usb_interface * INTF, 837 const struct usb_device_id * ID ); 838 839 void (* disconnect) (struct usb_interface * INTF ); Let's take a look at the parameter structusb_device_id, Which is needless to say. As we have already introduced, where does struct usb_interface come from? Let's start with struct usb_device. We know that each device corresponds to a s

interface descriptor. Row 3, struct us_unusual_dev, is the first occurrence of this struct, which is defined in drivers/USB/storage/USB. h: 61 struct us_unusual_dev { 62 constchar * vendorname; 63 const char * productname; 64 _ u8 useprotocol; 65 _ u8 usetransport; 66 int (* initfunction) (struct us_data *); 67 }; The find_unusual () function on the right of "=" is defined in drivers/

use another pointer to temporarily replace altsetting. Next we will use its members desc and endpoint. Looking back at structusb_host_interface, we can see its two members: struct usb_interface_descriptor desc and struct usb_host_endpoint * endpoint. Among them, desc is needless to say, it is the interface descriptor of this interface, and the endpoint pointer records several endpoints, they are stored in the form of an array, and the endpoint points to the array header. These are all set duri
