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 )

Most messages are from snd_printdd(), so it's no bug but verbose messages.

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

alsactl segfault seems irrelevant. Are you using the latest git version?

thanks,

Takashi

Thanks many, Fernando.
