I am attempting to power my Wiimote using a USB charger. It works fine when I hook it up to a computer USB port, but I want to mount the Wii remote on a projector and run power to it via the USB port on the projector. The projectors at my school have a USB-B port instead of a USB-A port for the charger so I used an adapter to change A to B, but I cannot get power from the projector to the Wiimote through this set up. I want to avoid using an AC adapter except as a last resort. can anyone help me?

Are you sure your projector have power on that usb connector ?

(I'm not sure when it comes to B connectors - try googling)

have you tried connecting it to a *powered* usb hub?

the connector type does not matter, it is just a different configuration of the 4 inputs of the usb. they dont make the type b kind much anymore because its just silly to have 2 different connectors to have to fight. but there still are places that use it instead of the type a slot.

with newer specs there is a difference in wiring diagrams but its just with the type a one wire is fitted to the ground and type b is not connected but this is generally in the micro and mini usb versions on cables that go from micro/mini to standard size

Details, details. Things to do. Things to get done. Don't bother me with details, just tell me when they're done.

USB A connectors are for hosts and B are for devices.  Hosts supply power to devices, so it makes sense that the +5 pin wouldn't supply power.  What other connectors does the projector have?

The usb on the projector is so the projector can connect to the computer.  Most likely this is so you can use your projector remote as mouse, more or less.  This being said, that means the projector does not supply the power from the usb on it.
