ECO1: Swap D11U pins
The diode D11U footprint and schematic pins are swapped. Correct this.
ECO2: Send USB pullups to VPP
The USB pullups on USBDN_RST and USBDP_LED are going to VUSB. They should instead go to VPP, otherwise USB will fail to function.
ECO3: Populate R15U with 1.5k, 10%
Enable low-speed USB operation by populating R15U with a 1.5k, 1% resistor.
