usbaudio: Too many audio streaming interfaces

[epronk]

I installed OSS4 on Debian squeeze following this HOWTO

This is written to /var/log/messages if I plug in my Logitech USB Headset:

Any ideas what causes this?
It should expose a stereo output and a mono input.

Try editing kernel/drv/oss_usb/ossusb.h and change "#define MAX_PORTC 8" line to something like "#define MAX_PORTC 16". Then rebuild and reinstall OSS and see if this error appears (it's a constant which is used as a limit for some reason).

It happens the 5th time I plugged it in.
I'm using the same port every time.
Notice that it used address 2, then 3,4,5,6

From my subjective point of view, such experiments do not make much sense.

USB audio devices are problematic with OSS4: "output is experimental, input is not implemented" https://wiki.archlinux.org/index.php/OSS

You may get much better sound quality with Profitec Analog Headset "CD 92 MV" (9 EURO) [sehr guter Klang]
