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.
