Abstract
A device and method for interconnecting two universal serial buses (USBs) is provided in which the device controls the current supplied to the device from the USBs via a power manager. In particular, when one or both of the buses connected to the device enter a suspended state, the power manager reduces the current consumed by the device so that the device does not exceed a maximum suspend current. The device may also have a power manager controller which permits one or both device drivers connected to the USBs to control the power manager.
