Hi Ning,

The PCM2900 does not have headset detection so I'm confused on what you are seeing. Can you give more detail on your issue?

Best regards,
Jeff McPherson

Dear

When the HOST is connected to the PCM2900 and other devices through the USB HUB chip, the PCM2900 connected to the camera will be disconnected, and the device connected to the non-camera will be normal.Pls help to check this issue.

Thanks

Hi Ning,

First be aware that the PCM2900 is not recommended for new designs. Also have you tried bypassing the USB HUB to isolate the issue between the hub or the device?

Thank you,
