Official Support

maxiscan contact email
mS509 help

Well I can begin with saying that their support and feedback is pathetic/10 and their english level is the same.
Official support email should be:  mailto:support@auteltech.com

Here are some examples of their "support":
MS509 scanner to usb cable pinout

problem with maxiscan ms509

So as you can see for yourself, their support is below the shitty-i-canspik-english-and-giv-technicl-supprt level.
