- Leave USB1_SS_RX/TX pin floating if USB3.0 is not implemented.
USB2_HS
- Connect USB2_HS_DP/DM to GND if USB2_HS is not used.
- We will use USB2_HS for AppsPort

QCT Schematic Review (4/9)
- Minimum total bus capacitance of 15 pF should be met
run simulation to make sure reflections do not violate threshold levels.
Used to mitigate possible HW issue.
