One aspect of the technology is an apparatus with a USB intermediate device such as a USB hub or a USB composite device. The USB intermediate device includes control circuitry that performs translation between USB 2 communications of the multiple downstream USB 2 ports and USB 3 SuperSpeed communications of the upstream USB 3 port. Another USB intermediate device includes control circuitry that modifies apportionment of the USB 3 maximum data rate among the multiple downstream USB 2 ports, such that the multiple downstream USB 2 ports communicate at a collective data rate exceeding a USB 2 maximum data rate of USB High Speed. Another USB intermediate device includes control circuitry that performs translation and modifies apportionment. Other aspects are a system with a host computer, methods, and computer readable media. |
