Abstract: Systems and methods for detecting Input/Output (I/O) device connection are described herein. The method includes physically coupling an I/O device to a host port through a first signal line and a second signal line. The method also includes driving the first signal line or the second signal line high via an active buffer of the I/O device. The method also includes providing an acknowledgement signal from the host to the device through the other signal line that is not being driven high by the active buffer of the I/O device.

Abstract: Systems and method for operating a low power universal serial bus are described herein. A universal serial bus port includes a link layer and protocol layer that are compatible with a standard USB2 protocol. The link layer and protocol layer to control a physical layer for transmitting and receiving data on a pair of signal lines. The physical layer includes a fully-digital Low-Speed/Full-Speed (LS/FS) transceiver to transmit and receive data on the pair signal lines using single-ended digital communications on the pair of signal lines.

Abstract: Described is an apparatus comprising a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be an elastic buffer coupled to a received clock, a local clock, a received-clock data, and a local-clock data. The second circuitry may assert a first flag when a set of values on the received-clock data matches part of a skip ordered set. The third circuitry may assert a second flag when a set of values on the local-clock data matches part of the skip ordered set. The fourth circuitry may increment a count value upon assertion of the first flag and may stop incrementing the count value upon assertion of the second flag. In some embodiments, additional circuitries may extract a first timestamp from a packet, sum the first timestamp and the count value, and substitute the sum for the first timestamp within the packet.

Abstract: Techniques for reducing idle power consumption of a port are described herein. An example method includes determining device presence using a pull-down resistor disposed in a downstream port. The method also includes initiating a low power state of a link between the downstream port and an upstream device. The method also includes disabling the pull-down resistor in response to initiating the low power state.

Abstract: Systems and methods for operating a universal serial bus are described herein. The method includes sending packet data from a USB2 device to a USB2 host on a pair of signal lines, and after sending the packet data, sending an End-Of-Packet (EOP) signal from the USB2 device to the USB2 host. The method also includes, entering the USB2 device into idle state after sending the EOP signal. The method also includes sending a digital ping from the USB2 device to the USB2 host to indicate device presence during idle state.
