Fw: Support for M-Audio VENOM?

Fw: Support for M-Audio VENOM?

Hello,

I would like to have support for the M-Audio Venom synthesizer. It has
a USB audio and USB MIDI interface, but the current usb audio driver
fails to configure it correctly : the system hangs during a long time
when the USB connection is established: for example, lsusb takes 24
seconds with the Venom attached, and alsamixer/aconnect -io end with 

As attachments, there is a .tar.xz with the output of lsusb, kernel
messages, dbus messages and /proc/asound contents.

What can I do to enable that USB interface?

I could help developers to help me having a working driver (I am
application developer, and I run Gentoo Linux).

Kind regards,
Xavier Miller.

This sounds like a basic problem with the Venom's firmware; there's
nothing much Linux can do about this.

with what?

Another firmware bug; but this device has only one sample rate, so the
driver should not treat this as a fatal error.

OK, thank you for the clear answer. Since M-Audio has abandoned the  
Venom, and since Avid pushes M-Audio to other kind of producs, I won't  
expect any firmware bugfix.

I will thus use a no-name USB-MIDI interface instead of the USB cable.
