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.

  1. unbelievable – so many problems – no efficient support – such expensive products – it is a SHAME for Pfaff – never ever again any Pfaff product for me – done

  2. i have a pfaff 2124 that a friend has given me to do some embroidery for them (and me). It has never been used. it has all the 3d software (ed file assistant, smart card reader, 3d embroidery artist,
    My question is this.. are none of these able to run on windows 7? i am very frustrated.
    Thank you

  3. 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.

  4. 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.

  5. 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.

  6. I recently had to reload all my programs from scratch onto a new windows 7 computer. I have 4D Embroidery Extra. I installed all the updates and the Hasp file. I am not able to transfer the designs to my 2170 any more. I get a flash of the transfer machine icon instead of the progress slide which normally appears while the file is being transferred; when I select send 1 which is my 2170.
    I notice Pfaff software and machine help files do not support 2170 machines nor the 4D software! I would be very pleased if anyone could help me get back on track. Thanks Dorothy

  7. Pfaff no longer supports the 2144/2170 and they apparently have no interest in supporting a machine that’s 12 years old. I have a 1929 Pfaff made in Kaiserslautern and it sews as well as my 2170 – WHICH IS NOW HALF A MACHINE because I cannot embroider with it. Not only do they no longer support the software required to transfer embroidery designs, but the 2170 firmware update is the last one they offered. Too bad.
    Pfaff, I expected better of you than this sloppy, careless lack of customer service.

  8. I cannot load any designs on my 2170 …. and am totally lost!! What a shame …. I won’t get another Pfaff. The card, which is connected to a usb won’t even work on XP.

  9. I need the drivers for the Pfaff cable to run on the 6D configure software. I have a Pfaff 2144. Any help would be appreciated.

  10. I have been having the same problem with my 2144 machine and my USB connection to my new computer with Windows 10. How do I install the driver to this USB connection?

  11. Raylene and Maria, just now seeing your posts. 6D is not compatible with the 2144. You must transfer designs using 5D.

  12. Jenny, I am unable to transfer embroidery from windows 10 through 4D to my Pfaff Creative 2140. I am using a usb to serial converter. I get an error message that it cannot open the comport. Hoping you can help!

  13. I have the opportunity to purchase a Pfaff 2170 for my daughter but am concerned about the embroidery software. Will she be able to transfer designs from her Windows 10 laptop using the cable thingy that comes with the machine?

  14. I have a 2140 which has been upgraded to the 2170 and of course now has no other updates. Last week, I received the following message when I connected my cable from my laptop to my machine (inserted card into card slot). “Unknown card type? Do you want to prepare the card for this system? All the information on this are will be lost? (Confirm with Ok).” NEXT SCREEN: “Deactivate write-protection!” At this point I can’t get the message off the screen until I take the card and cable out of the machine. I am now unable to access all of my designs on my laptop. Is this cable replaceable? Help!

  15. I have the same problem – can someone help us please? It has something to do with the Pfaff usb PC card that connects the machine to the computer. HELP PLEASE!

  16. I do enjoy my Pfaff 2170 and it sews beautifully. I was able to continue using the original 3D software that came with the embroidery attachment if I ran it on an old Windows XP computer. I download embroidery files off the internet onto a memory stick and load them into the old laptop to transfer files onto the machine. Seems to be working well. You may need to download drivers but I think the secret is to use an old Windows XP computer with the 3D software.

  17. Please help, I have the same problem. My PFAFF 2144 USB PC card has stopped working as well. Can the card itself be repaired?

  18. I have a Pfaff 2170 and 4D file assist. It worked fine with XP but I updated to Windows 8 and now can’t transfer my designs to my machine. I was told they are now not compatible. What a shame after spending all this money on the 2170. No help is offered from the company. You’d think they would at least try to have supplies so people could continue with what we first bought.
