Are high-bandwidth isochronous endpoints supported? If not, how hard would it be?

Hi there,
We're working on a board can can take in a massive number of microphones, and would like to be able stream them at a high sample rate too. The standard 1024 bytes/microframe is actually a bit limiting. So, I was wondering what it would take to make the the library support a high-bandwidth endpoint with the audio device.

Has anybody tried it? If not, what is the effort level required to support that?

Thanks!

It depends on MCU, though I think high-bandwidth ISO may take quite a lot of effort. You will need to dive into the work to actually know the amount of work

Thanks for the reply Ha! I was afraid of that. I guess we can scrape by with 24 or even 16-bit audio if it comes to that. We can look into it more if/when we need 300 microphones at once :-)

Thanks for the awesome library!

Hi, I am designing a high-bandwidth HID interface with the ESP32-S3 and I was wondering if 1024 byte per packet bulk endpoint is supported? Is it simply a matter of changing this value from 64 to 1024?:
