Alexander, can you attach the output from "lsusb -v" for this audio device?

--- Comment #4 from Alan Stern (stern@rowland.harvard.edu) ---
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.

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
--> https://bugzilla.kernel.org/attachment.cgi?id=290223&action=edit
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 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.

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.
