Hi Tiers.
I have a question about USB detection.
Below image is my system and REG08 description in datasheet.
Case 1 ) When 3G Module is not working (power off), REG08[7:6] is 01(USB port) or 10(Wall Charger), USB detection is good.
Case2 ) When 3G Module is working (power on), REG08[6:7] is always 00, unknow status.
Why case 2 is occured?
Even if case 2, I think VBUS_STAT have to be USB host or Adapter port.
Please let me know how can use ASAP.
Thanks.
