Pfaff Cable & Drivers

Hi Carolyn,

I think you have a great site and I am hoping, of all people, you can help me. I purchased a used 2144 last year and it has the 2170 software in it (so the dealer said). The 2144 comes with a cable that has one end intended to go into the 2144 card slot and the other end connects to a PC’s USB port. I am supposed to be able to transfer my designs from my PC in 3D Embroidery using File Assistant to the sewing machine. There is nothing in the sewing manual or the software manual about making the connections and getting the drivers to to run the PC/Cable/Sewing Machine connection. I am running 3D Embroidery on my old computer running XP. It was a nightmare trying to get it to run on my laptop with Vista or my brand new computer running a Vista 64-bit operating system.

Anyway, when I plug in the USB cable into the XP computer the dialog box comes up saying “Detected New Hardware” and begins the process of finding drivers for it. Of course, it cannot find any. To my knowledge there is not a driver CD disk that came with the cable connection that needs to be installed. I thought maybe there might be drivers on the 3D Embroidery CD disks that I inadvertantly did not install so I looked and I found two drivers for USB, that were not installed, but they were for the Viking.

I just don’t have a clue how to get the designs from the software to my machine. What should I do?

Thank you so much for this blog!


P.S. I do have a StitchLink II that came with all of this “stuff” I got in my package from the dealer the day I bought my Pfaff 2144. It is a wireless technology, but not really sure how to connect it all together either, but it does have a disk for drivers.


The 2144 originally had a serial pin cable to transfer designs to the SM. About the time that the 2170 was released the USB cable became available. The drivers for the cable are downloaded from the cable manufacturers site. If it is a belkin cable then  Belkin support will have the driver.  You will need to know the number of the cable to get the correct driver.  There are different drivers for XP and Vista.

The USB cable is only compatible with 3D File Assistant version 7 or later and will not work with earlier versions.  If this is the case you will need to get a USB Serial Adapter.  This converts a USB port to a serial port, which is how the earlier cables and versions of File Assistant worked. Three USB Serial Adapters that are compatible with the 2170 are:

- Belkin F5U103

- Belkin F5U109

- Keyspan USA-19QW

You should be able to get 3D running on Vista.  Drivers for the dongel are available on the Pfaff site.

    My Pfaff 2144 is my 3rd machine from this company. It seems that Pfaff does not want to address or even teach any of their technicians at the Pfaff dealerships about the problem of the non-functioning usb cable. All I keep getting from them is: Maybe you would like to upgrade your machine or “Ohh! You have and OLD machine!” If my driver search for the usb cable does not work, I will be changing brands to a more user friendly machine. I have had enough of their protectionisim tactics done only for their own good. I need machines that work with no hassles.

    I just got my Cable working after 1-1/2yrs of searching! Thank you all for sending me into the right direction which then led me to a website found by Google on how to resolve the problem.

    I had to load ALL the driver files from File Assistant to a temp file in my computer then went into the Microsoft menu for “devises & printers”, clicked on the icon for “2144 USB cable” then went into “properties”, clicked on “driver”, “update”. This then asked me where to get the files and I directed it to the tempoary file on my hard drive….

    So now, I can go back to enjoying my Pfaff machine and will not sell it.

    I have been using the Belkin driver to transfer designs for the last two years. Now all of a sudden, when I try to transfer a file to my Pfaff 2144, I get the message that “unable to open com port: 1.” What could have happened? It was such a hastle when I initially had to get it working. I had numerous problems getting Windows Vista to recognize the dongle. Now I don’t know what went wrong. The only changes recently were installing a new antivirus software and also using a malware product to get rid of some unwanted files. I went to the Belkin site and reinstalled the driver. I also checked in device manager to make sure the com port selected is 2. That was how it was working previously to this problem.
