These "No such device" errors when trying to enable the echocan are most 
likely the result of not having configured an echocan for the channel in 
/etc/dahdi/system.conf.

See line 309 in

These errors I don't know about off the top of my head (and they are 
probably the more critical ones for you I'm guessing).
