Some time ago I tried to use a usb-audio card on my new system and encountered some odd behaviour. The device appears in aplay -L but not in aplay -l. The controls are available in amixer/alsamixer, but changing settings does not have any effects. The device does not seem to be available to any other programs on the system. With some help from folks in #debian-next I managed to do a git bisect of the kernel and found the culprit. This is the commit that breaks this device for me: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ecaaef6b50a7873d495f9cc69fc4c4edfc792635 This device has been used successfully for nearly a decade without issues, but right now it is not functional at all. I had submitted a bug report at debian kernel team, but didn't get a response. So I 'escalated' it to this list. Any further information that is required I can of course provide.
I thought the fix is on its way. Reassigned the component to USB.
Alexander, can you attach the output from "lsusb -v" for this audio device?

Well, the problem is clear enough: Interface 5 uses endpoint 1-OUT in alternate setting 1, 1-IN in alternate setting 2, and both 1-OUT and 1-IN in alternate setting 3. At the same time, interface 7 alternate setting 1 uses endpoint 1-OUT and interface 8 alternate setting 1 uses endpoint 1-IN. According to the USB spec, different interfaces are not allowed to use the same endpoints. (The exact statement, in section 9.6.3 of the USB-2.0 specification, is: "An endpoint is not shared among interfaces within a single configuration unless the endpoint is used by alternate settings of the same interface." IMO the word "unless" should have been "except when".) This device would never pass the USB validation suite and would not be allowed to use the USB logo. Under the circumstances, it looks like interface 5 is not intended for general use, since it is described as Vendor-Specific. Does it get used in your system? The answer can be found in the /sys/kernel/debug/usb/devices file (with the device plugged in under an earlier kernel where it works okay). It may turn out that the way to deal with this problem is to add ENDPOINT_IGNORE quirks for interface 5 on this device.
In the current kernel, in /sys/kernel/debug/usb/devices, I see for this device: T: Bus=01 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#= 6 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=06f8 ProdID=b000 Rev= 1.00 S: Manufacturer=Hercules S: Product=Hercules DJ Console C:* #Ifs= 9 Cfg#= 1 Atr=80 MxPwr=300mA I:* If#= 0 Alt= 0 #EPs= 1 Cls=ff(vend.)

No need, this is good enough. We can see that there is no driver attached to If 5, so the quirk should work. I'll write it and attach it to the bug report soon.
Created attachment 290223 [details] patch for Hercules audio card Okay, this is the patch. It should prevent the kernel from paying attention to the endpoints in the vendor-specific interface, thereby removing the interference with the normal audio interface.
I will test this asap (early coming week). There is also another audio interface that has been giving issues since a recent kernel, but I will make a separate report about that.
Hmm, I tried this patch on the v5.6 tag of the stable repository (which is most similar to my current backports kernel I think) and it certainly does not work. I see the following in dmesg: [ 42.239255] usb 2-1.2: new full-speed USB device number 4 using ehci-pci [ 42.374832] usb 2-1.2: config 1 interface 7 altsetting 1 has a duplicate endpoint with address 0x1, skipping [ 42.374837] usb 2-1.2: config 1 interface 8 altsetting 1 has a duplicate endpoint with address 0x81, skipping [ 42.379986] usb 2-1.2: New USB device found, idVendor=06f8, idProduct=b000, bcdDevice= 1.00 [ 42.379990] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 42.379993] usb 2-1.2: Product: Hercules DJ Console [ 42.379996] usb 2-1.2: Manufacturer: Hercules [ 42.402543] mc: Linux media interface: v0.10 [ 42.410269] hid: raw HID events driver (C) Jiri Kosina [ 42.433713] usbcore: registered new interface driver usbhid [ 42.433716] usbhid: USB HID core driver [ 42.442887] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.449509] usb 2-1.2: 2:4: cannot get min/max values for control 8 (id 2) [ 42.449656] usbcore: registered new interface driver snd-usb-audio [ 42.462588] input: Hercules Hercules DJ Console as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.1/0003:06F8:B000.0001/input/input15 [ 42.483904] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.490524] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.497270] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.503843] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.510498] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.517260] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.519928] hid-generic 0003:06F8:B000.0001: input,hidraw0: USB HID v1.10 Joystick [Hercules Hercules DJ Console] on usb-0000:00:1d.0-1.2/input1 [ 42.520268] input: Hercules Hercules DJ Console as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.2/0003:06F8:B000.0002/input/input16 [ 42.520568] hid-generic 0003:06F8:B000.0002: input,hidraw1: USB HID v1.10 Mouse [Hercules Hercules DJ Console] on usb-0000:00:1d.0-1.2/input2 [ 42.520822] input: Hercules Hercules DJ Console as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.3/0003:06F8:B000.0003/input/input17 [ 42.523870] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.530509] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.537259] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.543908] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.550493] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.557242] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.563862] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.570484] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.577221] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.579585] hid-generic 0003:06F8:B000.0003: input,hidraw2: USB HID v1.10 Keyboard [Hercules Hercules DJ Console] on usb-0000:00:1d.0-1.2/input3 [ 42.587227] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.597243] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.624244] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 42.637479] usb 2-1.2: 2:4: cannot get min/max values for control 8 (id 2) Possibly I'm doing something wrong, as I'm not 100% confident in building my own kernels from source.
I just realized that the first part of your patch says `USB_DEVICE(0x0926, 0xb000)` but that should be `USB_DEVICE(0x06f8, 0xb000)` right?
You are right... It looks like I carelessly copied the value from the context line preceding the new entry in the second hunk instead of from the entry itself. Yes, please change that value to 0x06f8.
Ok, after correcting the vendor id the patch works! Or at least I can use the audio device. This is what dmesg looks like after this: [ 659.958338] usb 2-1.2: new full-speed USB device number 5 using ehci-pci [ 660.094151] usb 2-1.2: config 1 interface 5 altsetting 1 has a blacklisted endpoint with address 0x1, skipping [ 660.094156] usb 2-1.2: config 1 interface 5 altsetting 2 has a blacklisted endpoint with address 0x81, skipping [ 660.094159] usb 2-1.2: config 1 interface 5 altsetting 3 has a blacklisted endpoint with address 0x1, skipping [ 660.094163] usb 2-1.2: config 1 interface 5 altsetting 3 has a blacklisted endpoint with address 0x81, skipping [ 660.099333] usb 2-1.2: New USB device found, idVendor=06f8, idProduct=b000, bcdDevice= 1.00 [ 660.099337] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 660.099340] usb 2-1.2: Product: Hercules DJ Console [ 660.099342] usb 2-1.2: Manufacturer: Hercules [ 660.112369] input: Hercules Hercules DJ Console as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.1/0003:06F8:B000.0004/input/input18 [ 660.170829] hid-generic 0003:06F8:B000.0004: input,hidraw0: USB HID v1.10 Joystick [Hercules Hercules DJ Console] on usb-0000:00:1d.0-1.2/input1 [ 660.175755] input: Hercules Hercules DJ Console as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.2/0003:06F8:B000.0005/input/input19 [ 660.175968] hid-generic 0003:06F8:B000.0005: input,hidraw1: USB HID v1.10 Mouse [Hercules Hercules DJ Console] on usb-0000:00:1d.0-1.2/input2 [ 660.180114] input: Hercules Hercules DJ Console as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.3/0003:06F8:B000.0006/input/input20 [ 660.238640] hid-generic 0003:06F8:B000.0006: input,hidraw2: USB HID v1.10 Keyboard [Hercules Hercules DJ Console] on usb-0000:00:1d.0-1.2/input3 [ 660.249693] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.256389] usb 2-1.2: 2:4: cannot get min/max values for control 8 (id 2) [ 660.310086] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.316769] usb 2-1.2: 2:4: cannot get min/max values for control 8 (id 2) [ 660.323753] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.330373] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.337108] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.343735] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.350710] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.357459] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.364130] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.370791] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.377350] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.384164] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.390845] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.397335] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.404081] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.410711] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.417318] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.424073] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.430710] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.457353] usb 2-1.2: 6:4: cannot get min/max values for control 2 (id 6) [ 660.470711] usb 2-1.2: 2:4: cannot get min/max values for control 8 (id 2)
I've been using this version of the kernel on my laptop for a while now. The device works great again. Can we get this into mainline any time soon?
Sorry it took a while -- I lost track of this bug report until now. The patch has been submitted, so I think the bug report can be closed out.
