rpi-5.15.y drivers/usb/gadget uac2 not working in windows -> device cannot be started (error 10) #4587
Comments

5.15 isn't finished yet so this isn't a high priority, but if you have a guide to how to configure the Pi to replicate your setup that would increase the chances of it getting looked at (and possibly help somebody more familiar with the topic spot an error). |
|
The problem should be easy to reproduce. Compile the current 5.15 kernel and activate the g_audio module in /boot/cmdline.txt as discussed here: https://www.audiosciencereview.com/forum/index.php?threads/raspberry-pi-as-usb-to-i2s-adapter.8567/ After compiling and booting with the new kernel connect your Raspberry to a standard W10 PC via USB. The device manager will detect the new audio device but will not start it with error 10 (error: The specified range could not be found in the range list) I found some hints on the W10 UAC2 requirements here: https://docs.microsoft.com/en-us/windows-hardware/drivers/audio/usb-2-0-audio-drivers?source=docs |

I already did some experiments with using the same endpoint ID for the feedback and the data endpoint which I think is required when looking into the USB 2.0 spec (p272: "A feedback endpoint (explicit or implicit) needs to be associated with one (or more) isochronous data endpoints to which it provides feedback service. The association is based on endpoint number matching. A feedback endpoint always has the opposite direction from the data endpoint(s) it services." But this didn't help. Then I did some changes on bInterval and wMaxPacketSize for the feedback endpoint. But also without luck so far ... |

After changing the samplerate to 44100 and doing some other modifications the device windows manager doesn't show any errors but there are no audio endpoints created in windows. My USB descriptor now looks like this: ` Connection Status : 0x01 (Device is connected) Vendor ID : 0x1D6B (The Linux Foundation) Device Description : USB-Verbundgerät HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\1D6B01010515 Connection Index : 0x01 (Port 1) Connection Index : 0x01 (1) bLength : 0x12 (18 bytes) bLength : 0x09 (9 bytes) bLength : 0x08 (8 bytes) bLength : 0x09 (9 bytes) bLength : 0x09 (9 bytes) bLength : 0x08 (8 bytes) bLength : 0x08 (8 bytes) bLength : 0x11 (17 bytes) bLength : 0x12 (18 bytes) bLength : 0x11 (17 bytes) bLength : 0x12 (18 bytes) bLength : 0x0C (12 bytes) bLength : 0x0C (12 bytes) bLength : 0x07 (7 bytes) bLength : 0x09 (9 bytes) bLength : 0x09 (9 bytes) bLength : 0x10 (16 bytes) bLength : 0x06 (6 bytes) bLength : 0x07 (7 bytes) bLength : 0x08 (8 bytes) bLength : 0x07 (7 bytes) bLength : 0x09 (9 bytes) bLength : 0x09 (9 bytes) bLength : 0x10 (16 bytes) bLength : 0x06 (6 bytes) bLength : 0x07 (7 bytes) bLength : 0x08 (8 bytes) bLength : 0x0A (10 bytes) bLength : 0x09 (9 bytes) bLength : 0x08 (8 bytes) bLength : 0x09 (9 bytes) bLength : 0x09 (9 bytes) bLength : 0x08 (8 bytes) bLength : 0x08 (8 bytes) bLength : 0x11 (17 bytes) bLength : 0x12 (18 bytes) bLength : 0x11 (17 bytes) bLength : 0x12 (18 bytes) bLength : 0x0C (12 bytes) bLength : 0x0C (12 bytes) bLength : 0x07 (7 bytes) bLength : 0x09 (9 bytes) bLength : 0x09 (9 bytes) bLength : 0x10 (16 bytes) bLength : 0x06 (6 bytes) bLength : 0x07 (7 bytes) bLength : 0x08 (8 bytes) bLength : 0x07 (7 bytes) bLength : 0x09 (9 bytes) bLength : 0x09 (9 bytes) bLength : 0x10 (16 bytes) bLength : 0x06 (6 bytes) bLength : 0x07 (7 bytes) bLength : 0x08 (8 bytes) bLength : 0x04 (4 bytes) |

After several tests I found out that windows seems to be a little picky about the wTerminalType. After I changed these from UAC_OUTPUT_TERMINAL_UNDEFINED to UAC_OUTPUT_TERMINAL_SPEAKER and from UAC_INPUT_TERMINAL_UNDEFINED to UAC_INPUT_TERMINAL_MICROPHONE it started to work. |

Several users have reported that their Win10 does not enumerate UAC2 gadget with the existing wTerminalType set to UAC_INPUT_TERMINAL_UNDEFINED/UAC_INPUT_TERMINAL_UNDEFINED, e.g. raspberrypi/linux#4587 (comment). While the constant is officially defined by the USB terminal types document, e.g. XMOS firmware for UAC2 (commonly used for Win10) defines no undefined output terminal type in its usbaudio20.h header. Therefore wTerminalType of EP-IN is set to UAC_INPUT_TERMINAL_MICROPHONE and wTerminalType of EP-OUT to UAC_OUTPUT_TERMINAL_SPEAKER for the UAC2 gadget.

commit 5432184 upstream. Several users have reported that their Win10 does not enumerate UAC2 gadget with the existing wTerminalType set to UAC_INPUT_TERMINAL_UNDEFINED/UAC_INPUT_TERMINAL_UNDEFINED, e.g. raspberrypi/linux#4587 (comment). While the constant is officially defined by the USB terminal types document, e.g. XMOS firmware for UAC2 (commonly used for Win10) defines no undefined output terminal type in its usbaudio20.h header. Therefore wTerminalType of EP-IN is set to UAC_INPUT_TERMINAL_MICROPHONE and wTerminalType of EP-OUT to UAC_OUTPUT_TERMINAL_SPEAKER for the UAC2 gadget.

Hi all,
I've seen that there have been changes on UAC2 support for running the RPI as an audio usb gadget. I know that there have been problems in former versions and windows didn't properly connect, so you had to use UAC1. Now with the new feedback endpoint this should work, but I still have problems when compiling the latest rpi-5.15.y kernel on my RPI4. Windows detects it correct as UAC2 audio device but still says in device manager the device cannot be started (error 10). Does this work for anybody? Do I miss something when compiling the kernel? I've added the output of USB Device Tree Viewer below.
Thanks and best regards,
Johannes
