** Layout Note:1.Signal trace:8 mil

2.Power trace:30 mil3.CLK trace:10~15 mil4.DP,DM trace:15mil.5.The interval between the DP and DM measures 7.5mil.6.Any trace can't across the DP,DM and XI,XO.7.R6,C3 for card compatibility.8.R1,R2 for EMI reserve.9.R15,R16,C24,C25 for poor HOST USB signal reserve.
