Abstract:
1. A multi-processor or multi-chip device for selectively sharing a USB connection based upon whether or not concurrent tethered high-speed network access networking and USB data transfer is occurring in the device, comprising: a first processor; a USB hub operable to route a plurality of USB connections; a second processor coupled to the USB hub; at least a first switch coupled to a USB port of the device and configured to selectively couple the USB port to one of the first processor or to the USB hub; and wherein the first processor is configured to selectively share a USB connection based upon whether concurrent tethered high-speed network access networking and USB data transfer is occurring between an access terminal in said device communicatively connected to a peripheral device via said USB connections to enable or disable the USB hub; and wherein the first processor is configured to be emergency programmed when the USB port is coupled to the first processor via the first switch in a default configuration and subsequently selectively turns on the USB hub to enable emergency programming of the second processor via the USB port and USB hub.
