So one thing I didn't do is try the second cable I got a loan of, back onto my original Windows 10 machine. Did that, DS Downloader saw it right away and I was able to calibrate the tool and tune my car.

Thanks.

Here it is with the second cable I tried, the first one says the same thing.

I will once I get home from work - never had much time at lunch today.

If memory serves me correct, when I went into properties it said it was functioning correctly. By the time I'm home you folks will probably be gone for the day, I'll update this thread though.

Cheers

Another cable I have looks like this in the attached. Does the 7135 device itself have to be on a certain screen or anything?

Here is a screen cap, I'm going to try another cable

I have the baud rate set on both ends to 115200, I used the driver from the downloads section, and the DSDownloader cycles back and forth between COM1 and COM3 looking for the tool. (It's on COM3)

It's a gigaware usb-serial cable, I have no errors in device manager either.

I used PL2303_Prolific ...
