Is it possible that epoll() does not work properly with /dev/motmdm*?
I am debugging weird problems with ofonod, and that would be an
explanation...
epoll.poll() should be returning list of file descriptors and if they
are ready. And it seems to work for ttyUSB4 but not for motmdm.
Hmm. And motmdm_cdev_poll() lacks EPOLLOUT() support, right? That
could explain things...
Best regards,
