Abstract
A USB hub utilizes an external power supply connection and rechargeable battery to provide a fully functional USB hub that provides portable backup power for USB devices. The hub includes a housing with a host connector that is adapted to be coupled to a host. Device connectors are also positioned on the housing that are adapted to be coupled to electronic devices. A hub circuit enables USB communications between the devices and host connected to the hub. The rechargeable battery is selectively charged from the host or external power supply connection. A microcontroller controls the hub circuitry such that power is provided to the hub circuit and the device connectors from an external power source or host if available or the rechargeable battery if they are not.
