Hi all,
after some month I got back to this problem. Meanwhile theres a Linux
version 5.15.y available on github.com/raspberrypi that also includes the
feedback endpoint. Unfortunately it also doesnt work and the windows device
manager shows Device cannot be started (error 10). The specified range
could not be found in the range list. Ive already started an issue on
github https://github.com/raspberrypi/linux/issues/4587 . In addition is
there any windows logfile or tool that could help to find out which value or
which range is the root of the problem?
Thanks and best regards,
Johannes Freyberger

Betreff: UAC2 driver loaded but no audio endpoints visible
Hi all,
Im trying to use my Raspberry PI 4B as an UAC2 USB audio device for
windows. After I solved some problems around no feedback endpoint for an
asynchronous data OUT I can now see the UAC2 driver for my Raspberry is
loaded correct in the windows device manager, but it doesnt show any audio
endpoints. Probably the problem is on the Raspberry side but are there any
windows logfiles I could look at to find the cause of the problem? Or should
I check the USBPCap output in wireshark which I already did but Im not
sure what to search for.
Thanks and best regards,
Johannes Freyberger
