TUSB1310A - Errata RX.Detect Fail

Hi.

Our customer is having trouble can not recover from P3.

Could you please tell us in detail about the errata, "RX.Detect fails in P3" ?

I am understanding that one should use PIPE Power State in P2 instead of P3 when RX.Detect fails in P3.

But, normally I think the USB device receives the LGO_U2 or LGO_U3 packet from the host, then set the power state.

In this workaround, do you mean that you ignore the LGO_U3 packet and choose P2 power state ?

Best Regards,
Kawai

Please use P2 for both LGO_U2 and LGO_U3.
