Summary:Apparatuses relating to periodic Universal Serial Bus (USB) transaction scheduling at fractional bus intervals are described. In one embodiment, an apparatus includes a receptacle to receive a plug of a first device and a second device; a transceiver circuit coupled to the receptacle; and a controller circuit to: switch between a first mode for a first class of data transfers and a second mode for a second class of data transfers, wherein the first class preempts the second class of data transfers, schedule a data transfer with the transceiver circuit for a first endpoint of the first device at a first service interval of a bus interval when in the first mode, and schedule a data transfer with the transceiver circuit for a second, different endpoint of the second device at a second service interval that is smaller than the first service interval when in the first mode.
