Hello TI support Team,
I made a first USB DAC with PCM2706, it's Bus-powered. I modified Device descriptor data and it's working perfectly.
The sound is good enough for me but sometimes with ASIO4ALL drivers i can heard some 'glitch' (one for about 2 hours of listening).
So I would like to build another one which is self-powered. But from the datasheet :
- PSEL : Power source select (LOW: self-power, HIGH: bus-power)
- A condition of PSEL pin = High and HOST pin = High is needed to modify the descriptor data.
- the descriptor data modification in self-powered configuration (PSEL = Low) is not supported.
It is really impossible to manage to configure device descriptor data in self-powered mode ?
Can we put PSEL High at start up, and PSEL Low after device configuration ?
Thanks for your response,
and thank you for your work.
