Tool/software:

Hi Sir,

 My customer is using TPS65994 at host application. They test a U3 storage device with PD function, and there's no communication between PD and PCH when PD power on. But if we replug the U3 device. I2C2 will send IRQ and PCH will get 0x05 / 0x31 from 994's 0x5F register. What setting we can set at I2C2 mask to trigger PCH get PD status with the U3 device?

 We try to set the two item and it trigger IRQ indeed, but it didn't report the same 0x5f data as we replug the U3 device. (We get 0x05 only). FYI

Best regards,

Gary Teng
