I tested it this morning. Connected the cable to the PC, and to the ODBII connector inside the car.
Booted up the PC and turned the car on (two presses of the start button).
Once the Techstream interface came up, I selected Connect to Vehicle - this is the display that results:
After about 20 seconds, the PC beeps and this button appears at the bottom of the screen (sorry for the rotated image):
Clicking on it does nothing. Right-clicking opens this menu (sorry for the rotated image):
Selecting Close causes the Connect screen to disappear, and Techstream is locked up at that point. Clicking anywhere on the interface returns a Beep. Have to use Task Manager to kill the application.
Starting Techstream again, using the Cable diagnostics, I get this far:
After waiting about 4 minutes at this screen, this message appears:
When you click OK - Techstream closes.
Here's the version of the software:
I tried manually connecting, specifying Lexus, LS460, 2007 Model year. After the engine field is selected, the manual selection screen just closes.
I've tried the cable in different USB ports on the PC with the same results.
I'm thinking about trying an earlier version of Techstream...
Any other suggestions?
