How ttyUSB* created on my 3G modem problem
Hi

I would like to ask if someone knows the explaination of the /dev/ttyUSB*. I had a internet connection 3G usb dongle modem and need to restart before it detected the mobile broadband in the network manager. Before i reinstalled the lucyd lynxs i never meet this problem. But after i reinstalled the lucyd lynx i need to put the usb modem first before starting my system.. but if i plug my usb modem in a running state the network manager doesn't detect the mobile network therefore a remedy is plug first and restart.

One thing i notice if i had a working usb modem is i had a /dev/ttyUSB1-4 but if i plug it later and dont have a working usb modem.. i dont have the /dev/ttyUSB*.

I dont know if i this is the cause or the services that doesn't start if a plug the usb in running state..

Hope someone knows and understand my problem.

faxstate

FAXSTATE(8)                                                   System Manager's Manual                                                  FAXSTATE(8)

NAME

       faxstate - control ``modem state'' of a device used by HylaFAX

SYNOPSIS

       /usr/sbin/faxstate [ -q queue-dir ] [ -s state ] [ -n ] modem

DESCRIPTION

       faxstate  sends  a  message  to  the  HylaFAX  faxgetty(8) process servicing modem telling it to use the specified state when notifying the
       HylaFAX scheduler that a modem is ready and available for use.  This is useful for controlling outbound  use  of  a  modem;  by  marking  a
       modem's state as busy or down the HylaFAX scheduler will not assign any outbound jobs to the modem.

       The  specified  modem can either be the name (typically the last component of the terminal port the modem is attached to), or the full name
       of the associated FIFO named pipe file, e.g. ``FIFO.ttym2''.

       If the -n option, faxstate emulates what faxgetty would do; sending a message directly to the faxq  process  marking  the  specified  modem
       down,  busy,  or  ready.   This  interface is useful for send-only environments in which faxgetty processes are not used.  Note that modems
       manipulated in this way must previously have been configured with the faxmodem(8) program.

OPTIONS

       The following options are supported:

       -n        Contact faxq directly instead of faxgetty.

       -q dir    Use a spooling area other than /var/spool/hylafax.

       -s        Specify the state to send the faxq process each time the modem becomes ready for use; one of ``busy'', ``down'',  and  ``ready''.
                 The default state to use is ready.

FILES

       Consult hylafax-server(5) for a complete discussion of the structure and content of the spooling area.
