Hello.
The team at libusb says that this is a kernel issue so here it is.
Device : Sound Devices MixPre-D
This is an external audio interface that worked simultaneously as input
and output with older kernels and libusb versions (see far below with
fedora 26, kernel 4.13.13-200, libusb 0.1.5-8 from an older mothballed
machine).
With newer versions of the kernel and libusb it works only as output
(see just below with a current fedora 32, kernel 5.7.15-200,
libusb-0.1.5-16).
An online search shows that the dmesg output "duplicate endpoint" is
identical to the one referenced in this permalink :
http://archive.lwn.net:8080/linux-kernel/20200201105829.5682c887@acme7.acmenet/
So I guess that the solution is the same, adding in
drivers/usb/core/quirks.c (adapted to the specific hardware
identification) :
+ /* Sound Devices MixPre-D */
+ { USB_DEVICE(0x0926, 0x0208), .driver_info =
USB_QUIRK_ENDPOINT_BLACKLIST },
+
Would it be possible to add this exception to quirks.c ?
Thanks
Fedora 32

More than just this entry is needed; there also has to be an entry
listing the endpoints to be ignored. But that's straightforward to add.

Can you provide the output from "lsusb -v" for this device? We'd like
to know exactly what's being added to the ignore list and why, before
doing it.

Okay, this device does look a lot like the Sound Device USBPre2, so
the patch below should work. Please test it and let me know.
Warning: This patch was written for 5.9-rc2. It will require a little
adaptation to work with earlier kernel versions.

It works!
I had to adapt the patch replacing USB_QUIRK_ENDPOINT_IGNORE by
USB_QUIRK_ENDPOINT_BLACKLIST to compile with a 5.7.16 kernel.
Here is the dmesg output :
[ 71.735873] usb 3-9: new high-speed USB device number 4 using xhci_hcd
[ 71.862556] usb 3-9: config 1 interface 1 altsetting 3 has a

Thanks a lot.

* [PATCH] USB: quirks: Ignore duplicate endpoint on Sound Devices MixPre-D

To: Greg KH, Jean-Christophe Barnoud; +Cc: USB mailing list
The Sound Devices MixPre-D audio card suffers from the same defect
as the Sound Devices USBPre2: an endpoint shared between a normal
audio interface and a vendor-specific interface, in violation of the
USB spec. Since the USB core now treats duplicated endpoints as bugs
and ignores them, the audio endpoint isn't available and the card
can't be used for audio capture.
Along the same lines as commit bdd1b147b802 ("USB: quirks: blacklist
duplicate ep on Sound Devices USBPre2"), this patch adds a quirks
entry saying to ignore ep5in for interface 1, leaving it available for
use with standard audio interface 2.
