Hello,
I am using working on a usb audio device which has an Isochronous
Asynchronous output endpoint and an associated feedback endpoint.
The device uses UAC 1.0 and works at high speed and at full speed. When at
high speed does Windows expect the feedback endpoint to report 4 bytes of
data with a 16.16 format as stated in the usb 2.0 spec or should use the 3
byte 10.14 format for both high speed and full speed?
I saw a note in this post
//www.freelists.org/post/wdmaudiodev/USB20-High-speed-audio-device-for-windows-XP,15
but it is not clear to me what I should do.
Thanks for the advice,
