You have the oss driver loaded as well, which has stolen the card.
EVIL bad oss.
It's called  usb_midi,  crush kill destroy! You can blacklist the
module in modprobe.conf but make sure nothing autobreaks it, i.e each
time you boot rewriting modprobe.conf. I'd recommend compiling a
kernel with RT patches and without oss support. It's quite annoying
that mandriva has it still in the kernel. I'm still very happy with
the rest of mandriva.  If you are a new mandriva user
http://www.mde.djura.org/ is the best advice ;)
