I added some printks to motmdm_probe, and they don't appear to be called. I wonder if I'm missing something else in the config? I do have serial root@devuan:/my/ko# ls -al /dev/ttyS0 crw-rw---- 1 root dialout 4, 64 Dec 23 11:52 /dev/ttyS0 but not gsm multiplex: root@devuan:/my/ko# ls -al /dev/gsm* ls: cannot access '/dev/gsm*': No such file or directory Best regards, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
