Abstract: A Universal Serial Bus (USB) adapter includes a USB hub and a USB switch. The USB hub includes a plurality of downstream ports and one upstream port. The USB switch includes a plurality of connections that comprise a first connection configured to be coupled to a first USB apparatus, a second connection configured to be coupled to a second USB apparatus, a third connection coupled to the USB hub's upstream port, and a fourth connection coupled to one of the USB hub's downstream ports. The USB switch is configured to establish a first communication path between the first and second connections that bypasses the USB hub based on a determination that the first USB apparatus is to operate as a USB host, and to establish a second communication path through the USB hub based on a determination that the first USB apparatus is to operate as a client device.

Abstract: A signal conditioner can include a state machine configured to detect a predetermined protocol level mode of a data signal on a bi-directional serial bus. The signal conditioner can also include a re-driver configured to inject current into at least one of a rising edge and a falling edge of the data signal on the bi-directional serial bus in response to the detection of the predetermined protocol level mode.
