Its also not true that the chips work with the old drivers, at least the ones I had did not. I was on XP and installed the recommended older drivers and could connect to my ecm. But i couldnt log for more than a minute or two before the com port would crash (not sure if driver or hardware) and TP would lock right up until I disconnected the USB cable at which point TP came back to life but of course only counting data errors. Maybe with a smaller amount of data or at normal speeds they were more stable, or maybe whoever tested did not really give them a hammering, but I would not recommend using them for ALDL even if you do run the old driver.
