Status of GSoC 2022 proposal; status of currently implemented functions and protocols related to USB and USB audio

["Ethin Probst" <harlydavidsen@gmail.com>]

So this message is a bit of a question and an information dump; if you 
want me to split this off into two separate discussions that's fine by me.
First, I'm writing to inquire about the status of my proposal; I 
received some feedback and believe I corrected my proposal as directed, 
but unless it got lost in the flood of emails I get I have yet to hear 
anything about that, so I thought I'd inquire as to if anything has 
happened on that front.
Second, I've been digging through the EDK II sources (as of commit 
ee582858c4) and I've decided that it would be helpful to list all the 
functions/protocols that need implementation for my project. I'm however 
unsure how to scan for what and what is not implemented without writing 
an application and testing for each protocol. Is there a more efficient 
way for me to look for these?
