I'm having the same issue: specifically insufficient current being supplied through the USB ports. My power supply is the Rockman 200 power station... 12V/5amps. Attempting to debug this, I tried a wall-wart power supply - same thing. I then connected the ASIAIR Pro running 1.5.1 (6.92) to a bench power supply configured for 12V/5amp and measured the draw. After booting the AAP and wifi established, it's drawing 0.30 amps. When I connect the ZWO ASI120MM Mini camera to any port, the current draw does not change. It should have. When I connect my cell phone to these same port, the current draw only slightly increases (approx 0.38 amps). The camera & cable works fine when connected to my laptop running PHD2 and I can loop just fine. I suspect there is something in the firmware that's limiting the current flow through the usb ports. FYI, my serial number is 34cac3b2. I think you may have a bad batch, or a serious firmware bug. I know many others are successfully running the same configurations successfully.
