Cap Lite MicroUSB Port

What does This MicroUSB Port really do in this board?

Number of DC inputs 	1 (PoE-IN)

says that there is 1 PoE IN for this board

cap lite is the same as map lite, so usb port can be used only for power. you can power it by poe or usb or both

Does it will work with USB modem? OTG cable for microUSB-AB to USB 2.0 and more dc power on ethernet, like 0.5A , or 1A. (Standart is too low - 0.2A)

No, it is only for powering.

And if i will use USB Hub with additional power?
or CAPlite\map lite dont support USB host?? And cap just will not see USB device connected?

Cap will see nothing… it will just power on when connected to a usb port…

is this still true? I can see that it has microusb with ability to provide 1A 5V voltage.
