USB interface issues.

Post by bjacquot » Sun Feb 09, 2020 1:37 am

As noted here, I've been having a lot of trouble with connection external USB interfaces.

I happen to be a firmware developer myself, and have access to a USB sniffer. Would there be any value in trying to sniff the init sequences for my interfaces?

I have a USB analyzer here as well (for other projects), but it's of no use in iOS as Apple doesn't give developers any access to the stack at all. An interface either works or it doesn't unfortunately. They only thing we get is a stream of Audio and some basic ways to query channels etc.
