Hmm. What mewans ’serial’ in this case?

avrdude: usbdev_open(): did not find any (matching) USB device "usb:0" (0x03eb:0x2104)
avrdude: usbdev_open(): did not find any (matching) USB device "usb:4" (0x03eb:0x2104)
avrdude: usbdev_open(): did not find any (matching) USB device "usb:" (0x03eb:0x2104)

The avrdude package did install libftdi1, so I think its just an USB-to-serial converter?
