When HID device connect to the PC, HID devic driver announces which driver is loaded with a kernel info message. In this case, hiddev's minor number is always '0' even though hiddev's real minor number is another one. To display hiddev with minor number asked from usb core, we need to fill hiddev's minor number this interface is bound to.
