TUSB1002: Via count of USB layout

Part Number: TUSB1002

Hi Expert,

Since the layout guideline only said that it recommended to keep the via count to 2 or less.

May I know what happens if I need more than 2 vias?

From my perspective, more vias means more insertion loss, so if i need more than 2 vias, just make sure the loss of them would not affect the signal too much. am I making sense?

Thanks,

BR,
