Hi,
Version: 4.9 and uac1 driver is V5.9. I tested it based on 4.9 with backported dwc3 driver frome v5.9.
1. According to configfs-usb-gadget-uvc, PC(Windows 10) can get ISO data normally;
2. According to configfs-usb-gadget-uac1, PC(Windows 10) can install audio driver normally(AC Interface,/Captue Input terminal/Speaker);
3、uvc+uac1 composite device, PC(Windows 10) can get ISO data normally, but PC shows that the uac1 driver installation failed(AC Interface/Capture Inactive/Playback Inactive). AC Interface/Capture Inactive/Playback Inactive all show the device cannot start code 10, The settings of the I/O device are incorrect or the configuration parameters of the driver are incorrect. Through the USB analyzer to capture the packet, I found that the Index value seems to be wrong when PC host to get the descriptor. The acquisition is Playback Inactive and Capture Inactive, and the PC did not send the command packet about uac1. It is difficult to debug it.
I sincerely hope that everyone can give some suggestions or related patches to help me. Thanks very much!
Regards,
pengcheng

I suspect that some parts of the uac1 descriptor need to be modified,
but I don’t know which one to modify.
