Is the USB interface to SHARC and ADAU processors the same device?
I saw this SHARC processor that includes a USBi "for SHARC" and I don't know if that's marketing or if the SHARCs require a different interface.

In contrast to this USBi for ADAU 1401

Or is it a case of backward compatibility for the SHARC USBi?

So far as I can tell, USBi, is an Analog Devices term for their USB to I2C/SPI interface: USBi (EVAL-ADUSB2) [Analog Devices Wiki]
The ADAU 1401 part you mention is an Analog devices Sigma DSP Audio Processor. SHARC is their name for another group of DSP processors: Processors & DSP | Analog Devices
So, it seems that ADI use their USBi model USB to I2C/SPI interface for programming various of their DSP chips. Does the above help with what you wanted to know?

It appears the SHARC and ADAU1452 USBi devices are identical, at least the pin descriptions on the cases are the same. The ADAU1701 USBi device has different signal definitions on its case. So I would say no to your question.
Yes, I think this answered my question. They use different USBi devices. But I'm going to buy one of each and try. After I find out the answer I'll post again.
