Hello:
Posting in case anyone else has this issue with the AKASO camera(s). I have the 7000 USA (v1.1) version:
Apparently these cameras hate regular, generic micro-USB cables. I have success only when using cables that have the "B" label on them. Other micro-USB cables failed to work. Do not confuse this with USB TYPE-B. Literally the cable will have a "B" stamped on the receptor side of the cable.
Hope this helps,
