Dialup usb modem problem?

I installed the debian wheezy, and use Conexant dialup usb modem to connect the internet, the modem port is "/dev/ttyACM0".
It is working but suddenly it disconnect and get the error message:
rcvd [LCP EchoRep id=0x3 magic=0x4b729d27]
Modem hangup
Connect time 3.6 minutes.
Sent 245567 bytes, received 1100161 bytes.
Script /etc/ppp/ip-down started (pid 3261)
Connection terminated.
Script /etc/ppp/ip-down finished (pid 3261), status = 0x0
Failed to open /dev/ttyACM0: No such file or directory
Failed to open /dev/ttyACM0: No such file or directory
When i run the pon to connect the internet get the above error "Failed to open /dev/ttyACM0: No such file or directory", some times i disconnect the modem cable and then reconnect or sometime with reboot solve the problem.
When i check the "/dev" in meantime the "ttyACM0" is no more there, and come back with connection is established, lsusb show the modem connected with the system at meantime of error but with change of device id from "Device 006" to "Device 003".
How i solve this problem please?
