Tripp Lite's U052-06N-OTG-AM is a USB OTG (On-the-Go) cable that features a unique USB Micro-B / USB combo connector with a retractable USB Micro-B built into the standard USB A-Male connector. It acts as an OTG cable with the retractable Micro-B connector pulled out, connecting a USB device such as a keyboard, mouse, or flash drive to an OTG compliant Micro-B device. Push the retractable USB Micro-B connector back in to use the cable as a standard USB 2.0 A/A extension cable.
