It will be created automatically once you have the right driver. Go back to the kernel setup Device Drivers -> USB Support -> USB Serial Converter support, enable that as a module then under that enable the correct driver as a module. You might need to google a bit to find the correct driver from the list. Then you just; make modules && make modules_install modprobe usbserial this might autoload the correct driver, if not modprobe the drive you just built (the kernel source help should show the driver name). It might even be possible to build all the driver modules (if you cant find the right one) and allow the autoloading to load the correct one. I cant remember what works with that stuff. Here's what dmesg shows when i plug mine in - as you can see its a FTDI; [540721.409952] usb 6-1.3: new full-speed USB device number 5 using xhci_hcd [540721.503389] usb 6-1.3: New USB device found, idVendor=0403, idProduct=6001 [540721.503396] usb 6-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [540721.503401] usb 6-1.3: Product: FT232R USB UART [540721.503405] usb 6-1.3: Manufacturer: FTDI [540721.503409] usb 6-1.3: SerialNumber: A600E3MH [540721.535899] usbcore: registered new interface driver usbserial [540721.536982] usbcore: registered new interface driver ftdi_sio [540721.537006] usbserial: USB Serial support registered for FTDI USB Serial Device [540721.537100] ftdi_sio 6-1.3:1.0: FTDI USB Serial Device converter detected [540721.537147] usb 6-1.3: Detected FT232RL [540721.539219] usb 6-1.3: FTDI USB Serial Device converter now attached to ttyUSB0
