Hello all, A few days ago Leif determined that the USB DXE does not implement isochronous transfers. This will make USB Audio quite impossible as the audio data endpoint requires isochronous transfers.
I was looking at the EHCI driver but I can't determine a couple things: - Isochronous transfers have a different structure compared to other URB types. (Each URB type may have its own structure -- I haven't checked.) - I can't seem to figure out how this is handled in, say, EhciDxe. - If we were to try and implement this -- though I'm not quite sure how -- would we need to modify the PEIs too? -- Signed, Ethin D.
