Minimum value: High-speed termination resistor disabled, pull-up resistor connected. Only during reset, when both the hub and device
are capable of high-speed operation.
Recommended accuracy of the clock frequency is 50 ppm for the crystal and oscillator.
Suggested values for external capacitors when using a crystal are 22 pF to 27 pF.
