Comment 1 Takashi Iwai 2012-08-15 10:31:21 UTC

Looks like a left-over EP deactivation code in snd_usb_endpoint_start() causing the problem.  The deactivation should be called manually in the prepare callback, and let the start without sleeping.

Could you try the patch below?

Comment 2 Takashi Iwai 2012-08-15 10:39:32 UTC

Created attachment 77771 [details]
Test fix patch

Comment 3 WZab 2012-08-15 15:37:36 UTC

I've patched my kernel and recompiled it.
Now I get no kernel bug, but simply information:
[ 201.644625] cannot submit urb 0, error -28: not enough bandwidth
[  218.941094] cannot submit urb 0, error -28: not enough bandwidth
[  250.218323] cannot submit urb 0, error -28: not enough bandwidth
[  355.373665] cannot submit urb 0, error -28: not enough bandwidth

Now I'm trying recompilation of the fresh 3.5.1 sources, patched right after unpacking.

Comment 4 WZab 2012-08-15 16:44:21 UTC

Even after fresh recompilation of patched sources I get the same problem:

In kernel logs:
[  129.679542] cannot submit urb 0, error -28: not enough bandwidth

In qjackctl logs:
ALSA: prepare error for playback on "hw:1" (Broken pipe)
JackAudioDriver::ProcessAsync: read error, stopping...

So the patch prevents kernel bug, but also blocks proper initialization
of the USB sound capture...

Comment 5 Daniel Mack 2012-08-15 18:23:22 UTC

Which kernel did you use before and did does the same hardware work with that older version? IOW: Is this a regression?

Comment 6 WZab 2012-08-15 18:39:35 UTC

Before I used 3.4.5, and it didn't cause any problems.
I can try 3.4.9 and 3.5.2 and let you know about results.

Comment 7 WZab 2012-08-15 18:58:04 UTC

I have one more detail which may be important:

With the 3.5.1 kernel patched with the Takashi's patch the UGM96 works correctly, if connected directly to the USB connector of my machine.

The problem with:
  [7949.470578] cannot submit urb 0, error -28: not enough bandwidth
occurs only when the UGM96 is connected via the Hi-speed USB hub.
I've checked two hubs:

Bus 004 Device 011: ID 0a05:0001  
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            9 Hub
  bDeviceSubClass         0 Unused
  bDeviceProtocol         1 Single TT
  bMaxPacketSize0        64
  idVendor           0x0a05 
  idProduct          0x0001 
  bcdDevice            1.00
  iManufacturer           0 
  iProduct                1 USB2.0 Hub
  iSerial                 0 

Bus 004 Device 013: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            9 Hub
  bDeviceSubClass         0 Unused
  bDeviceProtocol         1 Single TT
  bMaxPacketSize0        64
  idVendor           0x05e3 Genesys Logic, Inc.
  idProduct          0x0608 USB-2.0 4-Port HUB
  bcdDevice            9.01
  iManufacturer           0 
  iProduct                1 USB2.0 Hub
  iSerial                 0 

and with both hubs the same problem occurred.

With the older 3.4.5 kernel UGM96 works correctly in all three cases (connected directly and via both hubs).

Comment 8 Daniel Mack 2012-08-15 19:09:16 UTC

Ok, the other bug might in fact be unrelated. We should definitely take Takashi's patch, and then ponder on the other one separately.

Comment 9 WZab 2012-08-15 21:17:03 UTC

The strangest thing, is that in the original 3.5.2 kernel both with UGM96 connected via hub and without hub, I was able to obtain sound capture (however finally the kernel generated bug:

Comment 10 WZab 2012-08-15 21:34:58 UTC

After applying the patch to 3.5.2, again capture works with UGM96 connected directly, and generates:
[  129.423617] cannot submit urb 0, error -28: not enough bandwidth
when UGM96 is connected via hub.

Comment 11 WZab 2012-08-15 21:48:01 UTC

Kernel 3.4.9 works with the same hardware - UGM96, both connected directly and via hub, without any problems.

Comment 12 Florian Mickler 2012-08-26 10:50:23 UTC

A patch referencing this bug report has been merged in Linux v3.6-rc3:

commit e9ba389c5ffc4dd29dfe17e00e48877302111135

    ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream

Comment 13 WZab 2012-08-27 18:47:19 UTC

Thanks for fixing the main bug, however the second problem, reported in comments #4 and #10 still exists. 
Should I re-report it as another bug (as the subject is not valid any more, it should be rather: "error -28: not enough bandwidth when USB audio capturee device is connected via USB hub")?

Comment 14 Alan 2012-08-28 14:30:32 UTC

Please open a second bug.. it's easier to manage that way

Comment 15 Daniel Mack 2012-08-29 11:24:07 UTC

The patch that was discussed earlier and which made it to mainline already does not do the right thing, I believe. Could you try this one on top of 3.6-rcX please?

Comment 18 WZab 2012-09-07 16:47:04 UTC

The attached patch (id=78751) doesn't work with kernel 3.5.3

Comment 19 Daniel Mack 2012-09-07 16:49:13 UTC

The patch has already been merged as other people signalled success in testing it. Please go ahead and try Linus' current master branch.

The patch has been marked for stable@ and should be picked up soon.

Comment 20 WZab 2012-09-07 16:54:30 UTC

OK. I can see, that it should be aplied AFTER the previous patch!

Comment 21 WZab 2012-09-07 17:44:21 UTC

With kernel 3.5.3 compiled with both above patches applied:

When tried to start UGM96 connected via hub - system froze immediately. I had to switch the power off.

When tried to start UGM96 connected directly, I got the following error:
[  113.313284] retire_capture_urb: 3720 callbacks suppressed
[  159.005496] cannot submit urb 0, error -28: not enough bandwidth

Comment 22 Daniel Mack 2012-09-07 17:46:13 UTC

Please try Linus' master branch. There were some other patches for this drivers as well.

Comment 23 WZab 2012-09-07 20:10:36 UTC

I've checked 3.6-rc4.
There are still problems:
with hub - [  137.929189] cannot submit urb 0, error -28: not enough bandwidth

without hub - [  188.164687] retire_capture_urb: 4419 callbacks suppressed
[  188.188062] cannot submit urb 0, error -28: not enough bandwidth

(but these may be different problems - related rather to bug 
https://bugzilla.kernel.org/show_bug.cgi?id=47201 ?

Comment 24 Takashi Iwai 2013-11-15 15:38:27 UTC

The bandwidth issue is not about the sound driver but rather a problem with usb host controller.  If this still happens with 3.12 kernel, please open another bug report.  In that case, it'd be also helpful to test sound.git tree (for-linus branch) as well, since some usb-audio fixes are there for 3.13-rc1.
