Hi, Dimitri,

This issue is addressed here.

If you aren't using those types of quantities, we have some devices that have the ability to program the descriptor via SPI/I2C, as well as a ROM interface. Look at PCM2704C/PCM2705C/PCM2706C/PCM2707C for example.

Thank You for fast and complete answer,

suggested devices are DAC's. But I need the record-funktion of PCM2903B. Actually I'm loocking for 2.0 USB-Device (USB-Audio-Codec) with two channels and modifiable descriptors.

Dimitri,

I don't know on this device, but it might be worth a look from you: TMS320C5532
