Autocom CDP Cars update

[carterdins]

Hello. This is my first post. I hope not post in a wrong place.

 

And, the problem is,

I have a Autocom cdp for cars china clone, and want to update.

I thought I just need to connect autocom to computer and press update, but it shows no power supply is connected.

I can see on the autocom device that the LINK is on but not power, it gives me 3 options or faqs

1: no power is connected

2: wrong com port

3: the USB is wrong connected

 

What am I suppose to do now?

Please help. Thanks in advance!
