hi all I need to write a driver for a new USB device from some 'X' manufacturer. Since they havent supported their device on linux, i guess they dont have any device ID as such. Can i write the driver for such a completely new USB device from user space? By using libusb or usbdevfs API? Which of them shall be better ,in case i can write one in user space?
