Maybe you can find solution faster than me, I think it is something with not existing luna/gateware/debug directory in usb2-highspeed-core but that's my guess.

I've ported this to a ecp5 with a usb3300, I can get the board to enumerate, but only by cutting the descriptor back.

If I comment out create_output_streaming_interface() and create_input_streaming_interface(), it enumerates fine with a URB length of 119 bytes.

If I include a single AudioStreamingInterfaceDescriptorEmitter() under either the input or output descriptor it also enumerates fine, with a URB length of 128 bytes.

If I include the AudioStreamingInterfaceDescriptorEmitter()s in both the input and output descriptors, I get a Protocol Error -71 at the GET DESCRIPTOR Response DEVICE stage, it doesn't get far enough to even report the length of the descriptor. in dmesg that's a device descriptor read/64, error -71

This smells vaguely like https://github.com/greatscottgadgets/luna/issues/86, but I'm definitely running the fix from that. I'd report this under GSG Luna, but I'm not sure how much I'm leaning on upstream patches from https://github.com/amaranth-community-unofficial/usb2-highspeed-core

Hello,

On Linux (Ubuntu 20.04.3 LTS) latest code (from branch 'main') does not work properly: after 2-3 minutes of normal playback there is loud noise (something like white noise). It is caused by overflow in ep1_out fifo, what leads to malformed state of USBStreamToChannels.

By comparing latest code with version 0.2.0 (on which everything works correctly) I found that commit 2783e77f934e17a5dc8b15de83cded22a651a560 causes such behavior. After revert everything works properly.

I was trying to fix it by my own, but I don't know that much about USB, so I am living this issue to you.

I had this codebase building last year, but pip is giving me some sass this time around Apparently the new pip version resolver gets angry about subtle URL string mismatches

In this case, luna specifies a trailing @main in some git URLs (yes, really, that's enough to upset pip now)

The conflict is caused by:
    The user requested amaranth 0.4.dev5+gc6dc08c (from git+https://github.com/amaranth-lang/amaranth.git)
    amaranth-boards 0.1.dev236+g809587c depends on amaranth<=4 and >=0.2
    luna 0.1.0.dev0 depends on amaranth 0.4.dev5+gc6dc08c (from git+https://github.com/amaranth-lang/[email protected])

I consider this a bug in pip, the (temporary and extremely brittle) workaround is to tweak the requirements.txt to match precisely the URLs listed in luna

The following completes pip resolution, but I had to point to the wrong amaranth-boards.git.

Thanks for the link to retroramblings, that article was useful. I'll follow this up with a resolution next week when I bully pip into giving me the repos I need.
