Enable USB2 on 40 way header

#1

I want to enable the USB2 DP / DM connections on the 40 way header but cannot locate R45 and R46.

Can I please have a PCB layout with the locations marked? Also the schematic doesn’t specify a value so I assume they are 0 ohms.

Thanks

The resistors for USB nets are not installed. You need to remove the zero ohms resistors from I2S and install them un the USB circuit. They are incredible small and requres profesional equipment.
Step 2 the software…
