1.

Measured at A plug.

2.

Measured at A receptacle.

3.

Measured at B receptacle.

4.

Measured at A or B connector.

5.

Measured with RL of 1.425 kΩ to 3.6 V.

6.

Measured with RL of 14.25 kΩ to GND.

7.

Timing difference between the differential data signals.

8.

Measured at crossover point of differential data signals.

9.

The maximum load specification is the maximum effective capacitive load allowed that meets the target VBUS drop of 330 

mV.

10.

Excluding the first transition from the Idle state.

11.

The two transitions should be a (nominal) bit time apart.

12.

For both transitions of differential signaling.

13.

Must accept as valid EOP.

14.

Single-ended capacitance of D+ or D- is the capacitance of D+/D- to all other conductors and, if present, shield in the 

cable. That is, to measure the single-ended capacitance of D+, short D-, VBUS, GND, and the shield line together and 

measure the capacitance of D+ to the other conductors.

15.

For high power devices (non-hubs) when enabled for remote wakeup.
