I have an android tablet. It does not have bluetooth. It has one micro-usb port and no other usb ports. My keyboard for the tablet has a micro usb connector and that's what stays in the micro usb port all the time. I need another usb port or more. I cannot find a hub with an open micro usb port for the keyboard. Anyone have a link or an idea where I can get a usb hub with an open micro usb port? Is there a way to do it that I'm not noticing?
