Hi
That is a totally different issue. That might happen if you disconnect
your modem from the PC and reinsert it. Maybe this also happens if you
turn it off/on. This shouldn´t happen "by itself" since /dev/tty is
defined by kernel on device detection.
There is a workaround predefining the /dev/xxx for the usb device but
didn´t remember how it is done.
Regards
Alvaro
