How do I read the device number of a usb device? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. I made a usb driver (based on the usb Kernel code of course) and wanted to use a usb device to test whether data can be transmitted. But the device Number of the usb device (made by others, new devices) is unknown and cannot be connected to the driver .. You cannot set the port number for reading data in the program .. Which of the following is a great reminder .. I want to use bus hound to check the information, but I cannot find any information such as the device number ..

Or which of the following methods can be used to connect to a usb device. Thank you ~
