Not sure how to do that...  am I wrong in assuming that the endpoint values I
need are in the output of lsusb -v?

This is where it stands right now... the capture part is working fine with
the addition of the specific endpoint address, playback either crashes JACK
or hard freezes the R16.

            .ifnum = 4,
            .type = QUIRK_AUDIO_FIXED_ENDPOINT,
            .data = & (const struct audioformat) {
               .formats = SNDRV_PCM_FMTBIT_S24_LE,
               .channels = 8,
               .iface = 1,
               .altsetting = 1,
               .altset_idx = 1,
               .attributes = UAC_EP_CS_ATTR_SAMPLE_RATE,
