The default setting for USB High Speed Squelch Threshold results in a threshold close to or lower than 100mV. This leads to Receive Compliance test failure for a 100mV threshold.
The changes shift the threshold from ~100mV towards ~130mV resulting in passing of USB High Speed Receiver Sensitivity Compliance test.
