[Freeswitch-users] mod_gsmopen - deadlock tty

[Giovanni Maruzzelli]

This seems to be a kernel problem.

To have the most success chances: use a USB hub with power supply (eg, a
USB hub that get electrical power from the wall socket).
Also, use the reference.platform, debian 8 jessie, instead of freebsd.
