Hi Guys,
Hoping somebody can help! I'm trying to read an used ecu thru the OBD port on a B5.
I'm getting a "unable to open comport" (error=0x01) message. I've tried ports 1, 2 & 3, not sure how else to aproach this....currently hooked up to the car!....Thanks.

that is about as a cut and dry problem as you can get.
the most obvious question, which com port is for your cable?

I agree! lol.... I checked and it's on port 3 (Port_#0003.Hub_#0001) baud rate is 10400 |

usb does not equal com. in device manager, under ports (com and lpt), thats where its listed. |

Thanks for getting me on track Komp, I know exactly what you're talking about, and it's been a long time since I had seen it. (I had originally looked at properties for the USB port I was connected to, to determine the com port as I hadn't seen com & lpt.). When I searched device manager, guess what? I was missing "com & lpt" off the tree. I googled why and I was not alone! windows 7 is missing it. so I had to add it by doing a hardware add (which is also missing), then do a search for "hdwwiz" under the start menu, and the hardware wizard comes up. I added the com & lpt to the device manager tree and now it shows. However com 5 & com 6 which now show, have a yellow exclamation on them, which I think means I have to transfer the USB communication to either com5 or 6 to identify the location. So, my head is about to explode and my wife is hunting me down, therefore, I'm calling it a night and let you know how I make out tomorrow.....man, thanks for being patient.  |

That's not going to work. If installing the driver didn't add COM ports you did something wrong or are using the wrong driver. |

This is what i did today: I un-installed the ftdi driver and re-installed it, this time instead of it being usb converter a, it's just serial bus converter and it's working properly. Unfortunately, my results are the same  This is my command line if anyone can see something, please, fire away  Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation.

the phrase you can lead a horse to water but you cant make him drink comes to mind here.
again, how did you come to the conclusion that its port 3? because obviously, its not.

Komp and nyet....here's a screen shot of both the device manager and the usb converter showing what I thought was the comport. (remember, I added com & lpt last night to the tree and I agree with you both of you that it shouldn't be as complicated to assign a comport as it is getting to be!). I was able to read the ecu and pin throught the OBD with the regular vag tacho software cd i have, however, when I try to access the ecu with argdub's tool, I'm one step short, believe me, I appreciate the effort you guys are making, and I'm trying not to overlook something.  |

You need to be using the VIRTUAL COMPORT DRIVERS (VCP). Download them, and manually install.
