FWIW my $15 knockoff cable and burned copy of techstream from amazon worked just fine for me and was super handy in diagnosing some stuff on my LX 100 series.
Plugged it into the 4runner and had no errors or issues either. That said, I didn't look into fuel trim, but it connected without issue and let me go through the available systems.
Maybe re-install the software?
It turned out being a problem with the newest update of Techstream. I tried an older version and it worked fine, nothing wrong with the cable it ECM.
