Description of problem:
Attempted to use a Huawei E226 modem using ModemManager
SELinux is preventing pppd from 'create' accesses on the archivo LCK..ttyUSB0.

*****  Plugin catchall (100. confidence) suggests   **************************

Si cree que de manera predeterminada se debería permitir a pppd el acceso create sobre  LCK..ttyUSB0 file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso temporalmente ejecutando:
# ausearch -c 'pppd' --raw | audit2allow -M mi-pppd
# semodule -X 300 -i mi-pppd.pp
