I have Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-33-generic x86_64) and Asterisk 11.7.0~dfsg-1ubuntu1 with DAHDI Version: 2.10.0.
I’ve successfully used my TDM400P for many years on that machine, but for unknown reasons I’m not able to load driver anymore.
Here’s what I get:
modprobe: ERROR: could not insert ‘wctdm’: Invalid argument
I’ve search a lot on forums and I’m not able to find someone with the same issue.
