An improved USB connection is disclosed that includes a pair of host parallel resistors connected to the USB connection at the host termination and a pair of peripheral parallel resistors connected to the USB connection at the peripheral termination. During high speed operation, the parallel resistors are switched to ground. Another aspect of the present invention is a voltage pull up apparatus for a USB connection. The apparatus includes a pull down resistor connected to the USB connection, a trickle current source attached to the USB connection, and a boost current source attached to the USB connection.
