Frustration... weekend before last was over at a local guy's house and ended up messing around with coding... I hadn't got my laptop completely set up yet because I was stuck on communication w/ car, but we figured it out.

But I knew laptop was dying so I bought a new hard drive for it and cloned the old one. Well apparently the HDD had bad sectors on the Windows partition so I can't get it to work now.

So I bought a new laptop running Win7. Got it to the point where I was almost back to where I was. Now when I plug my cable into the USB port it does not find any drivers for it, whereas on my old (Vista) laptop it just worked.

I tried loading the drivers from the CD that came with the cable but that didn't work either. When I look at device manager it has "Unknown Device" and "D-CAN" neither of which have drivers installed.

I'm sure I'm missing something stupid, so if someone can give me a pointer to whatever I need to do to make this work so I can get back up and running I'd appreciate it.

Right now I'm going back to a previous restore point so I can start clean again... grr...

If you see your cable as "Unknown device" that means that it is broken.
Send it back to the seller and ask them for replacing.

You should always use drivers from this site:

You can try with different computer, but I think that cable is broken.

Good luck.

Hi Pawel,

I *think* I figured it out.

A fresh install of Win7 has searching for drivers disabled. I did not realize this and the error message gave no indication of this.

I've enabled searching Windows Update for drivers and the cable drivers installed correctly.

Now here's the weird thing, apparently BMW Standard Tools deleted all of its files when it installed, and then I restored to before I'd installed it, so now I have to copy all the files back over from my portable HDD.

In a couple hours, I should be where I was a week and a half ago :/ I hate computers sometimes...

The cable I have does use a FTDI chip so if it hadn't worked automatically your link would have been exactly what I needed.

it's funny you mention this because I had the same problem on my Windows 7 64-Bit laptop, it wouldn't find the drivers automatically so I had to find USB Drivers for the cable and install them manually, first time it recognized it as a USB but didn't work so I opened it up in the Device Manager and updated it again using the same files and then it recognized it as a COM PORT.

[N8N]

Yes mine is 64-bit as well. But so was my old Vista machine...

once I reinstall the tools hopefully all I have to do is set the cable to COM1 and latency to zero (the latter is what we missed previously) and then bring my daten files in etc. etc. etc.

[N8N]

OK I got the black dots... woohoo!

Had to change latency to 1 and xmit & rcv bytes to 2048 that was it (for my COM port through device manager)

now I'm stuck on getting my daten files loaded... and I don't have a profile

going to get some lunch and hit it again this PM and hopefully report success

Lets hope changing the rcv bytes works out, my cable worked for flashing the Alpina tcu a few months back. But today it can't detect the ignition.

How do you update the cable to work on 2008+ cars?
