All serial cables that are marked with DAU-9(P) or DLR-3(P) or DAU-05 should be supported. If there are any problems (not related with hardware failure) please let us know.

The CA-42 runs the standard usb-to-serial protocol (usbcdc). Thus the usbserial driver can be used. Before plugging the cable use the insmod to bind the usbserial driver to the cable: insmod usbserial vendor=0x0421 product=0x0802. As soon as you plug in the cable a /dev/ttyACMX node should be created.

In case when ids are not in the module sources, you need to add them and recompile the module (no need to recompile whole kernel).

The CA-42 Clone cable from uses the Prolific PL2303 Driver. Since 2.6.16 the Linux kernel correctly supports this device:


Once this is taken care of, gnokii will be able to use /dev/ttyUSB0 as a serial port.

Serial cables, DKU-5 and CA-42 are known also as Pop-Port connections and are discontinued since 2007. Therefore if you have the phone that was manufactured after that date have a look at one of he cables below.

DKU-2, CA-53 and CA-70

DKU-2 cables are not seen by libusb unless there's a phone attached. I'm not an USB expert but that probably means that all communication, transformation logic is done by the phone, the cable is the silly transmitter (ie. the cable is not usb-to-serial converter).

CA-53 cable is a replacement for DKU-2. CA-70 is even newer replacement which adds to the CA-53 a connector to charge the phone drawing power from the USB port.

DKU-2 and CA-53 (and most likely CA-70) cables are supported by gnokii userspace driver using libusb (works on Linux and partially on FreeBSD). There is also kernel driver nokia_dku2 provided in gnokii sources, but it turned out not to be reliable and hard to maintain (due to large number of the mobile phones). Writing it correctly seemed to be too much work so the driver got deprecated. See also more detailed DKU-2 information.


DKE-2 cables are just adapters from USB to mini-USB, with a male USB A and a mini-USB B connector.

You can use the cdc_acm kernel module which creates a /dev/ttyACM* device file compatible only with gnokii AT driver so you might get more functionality with a FBUS using connection = dku2libusb (or via Bluetooth or IrDA).

  • config: Linux (Ubuntu Hardy 8.04: 2.6.24-16-generic), DKE-2 cable using gnokii driver for libusb
model = series40
port = 1
connection = dku2libusb
  • config: Linux (Ubuntu Hardy 8.04: 2.6.24-16-generic), DKE-2 cable using Linux kernel driver for cdc_acm
model = AT
port = /dev/ttyACM0
connection = serial


It's a data and charging cable similar to DKE-2 (which is only a data cable) for phones that can be charged from an USB port. Should work with dku2libusb. See examples for DKE-2 above.

The connector on the phone end is a Micro-B USB. When shopping for a cable, please note that Micro-AB cables are widely available and they do have different mechanical characteristics.

Probably a variation of CA-101 for phones that have a round charging connector. Should work with dku2libusb. See examples for DKE-2 above.

The connectors on the phone end are a Micro-B USB and a charger plug.

PL2303 based cables

For reliable communication the following command may be needed to be issued before talking to the phone[1]:

stty -F /dev/ttyUSB0 9600


You'll find the USB compatibility table at Nokia site.


If you got communication timeout it means that gnokii does not receive any answer from the phone. In general there are two major reasons for that:
