Having a similar problem, the laptop is recognizing my usb to serial adapter when plugged in but no driver has worked for it, even the driver sent with the cable, when i open device manager on my windows (xp) it shows up the yellow triangles which i assume is a problem with the driver?
I don't remeber exactly how it went but I drove myself nuts with something I thought was device manager related.
It turns out that device manager will only display things correctly when the cable is plugged in.

Do you have the DIY adapter or another brand ?
Their adapter comes with the driver and the driver can also be down loaded from the DIY site.
The DIY site also has a utility that helps you sort out comm problems - don't know what it is called.
I had problems connecting to Megatune only using a Rat Schack cable/adapter but was able to connect to Tuner Studio. When I got the DIY adapter I was able to connect to both programs.
You may want to email matt. He helped me out a lot with my issues ( matt@diyautotune.com )

If you have DIY's adapter you can also down load the driver straight from them....
Did you do searches under "Communication Problems" and stuff like that. I think we have had issues with connectivity.

I'm stumped.
I haven't tried to connect to my MS in a few months but last time I did everything was fine.... Today I can't connect to Logworks,Megatune or Tuner Studio.
Tried all the ports, tried Ports Check and it tells me there are 2 ports open. The lap top makes that "Bing" sound when I plug and unplug the cable.
I downloaded the driver for my adapter from DIY again and I still can't connect to any of the above programs !!!!!!!!!!!!!!!!!

What type of laptop do you have? I would suggest trying a different laptop and see if that works. You might also want to go to a local goodwill and see if they have any old laptops for sale. I recently picked one up for $25 that had a real serial port and it works great for running TunerStudio.
I meant the COM port number, sorry for not making that clear.
