Hello all,

    following is an extract of kern.log when connecting and disconecting a 
TASCAM US122L :
( the pcm part of the us122L does not appear in /proc/asound/... but only 
the midi part.
  kernel : 2.6.27-rc5-git11, alsa-driver-1.0.18rc3 compiled separately of 
the kernel sources, alsa-lib-1.0.18rc3 and  alsa-utils-1.0.18rc3 )

I'd appreciate some ideas about the segfault in alsactl and the ausence of 
the pcm functionality..
Thanks many,
    Fernando.
