Re: Embedded NetBSD USB
Of course it is a non-ehci version. I need to be an audio device sitting across
a cable from a pc that would be the host. Sounds like I am on my own on this
Thanks for your response

Is that Synopsys EHCI compliant core or the non-EHCI one? If its the latter, I
feel your pain.

So you want to "act" as a USB audio device? Plug your device into a USB host
and have it attach as a USB audio deivce?
Or do you want to attach a USB audio device and have it discovered and used?
The NetBSD USB stack is a host-only stack. Why there are several systems that
could act in USB device mode, they do their own things when it comes to device
