You can copy the code from libusb into your own program, if you're willing to follow the license requirements. > I just want following information from system/kernel to my module like, > idvendor,idproduct, bus_info, system device name? > Bus info should be like we use in /dev/video0? is there any way to do this? > in short i would like to make path equivalant to *usb_make_path()? how can i > achive this ? You can look through the directories under /sys/bus/usb/devices/. Ignore directory names that start with "usb" or that contain a ':', because they don't refer to external devices. Within each of the remaining directories, the vendor ID is in a file named idVendor and the product ID is in a file named idProduct. I don't know what you mean by "bus_info" or "system device name".
