Tahwo is USB-Fbas transceiver, R2007 is EMI filter. When Tahwo is good, good R2007, good mini USB connector and good usb cable - you will always hear windows sound: "Ti-Dii". Therefore:

1. Check usb cable.
2. Check pin2(D-), pin3(D+) from mini USB connector to point 2 and 3 in J2060 area.
3. Check Vbus at C2313.





If all OK, then replace Tahwo.
