A system and method for emulating a universal serial bus device is disclosed. An example embodiment may include an emulated USB (EUP) device that can emulate a host side of a USB connection. This device may have a microcontroller that is programmable with software to emulate a host connection of a physical USB device. In order to emulate a host connection of a USB device, the EUP device may configure USB host mode bus signals, initiate USB frames on the bus, indicate device status to an emulation process, and relay packets between a device and the emulation process.
