Operating system name and version: Ubuntu 9.10 32-bit
Name and model of a modem / phone: Nokia CS-15
Interface: USB

Hi,

Has anybody got following error, from syslog:

May 01 12:12:12 smsserver kernel: [25515.152706] usb 1-1: USB disconnect, address 2

I've tried with ubuntu 9.10 and 10.04 but same thing with both versions. That doesnt have any specific time or time period when it happens, it does it randomly.
Is it possibly that Nokia's usb stick what does it?
Everything works like charm until that message. After message smsd service stops and device changes its place (from ttyACM0 to fe. ttyACM1).
Is that familiar problem to anybody or do i have to just change modem?

Message is from kernel so probably it has nothing to do with sms server tools but here's my smsd.conf anyway:
devices = GSM1 outgoing = /var/spool/sms/outgoing checked = /var/spool/sms/checked incoming = /var/spool/sms/incoming #sent = /var/spool/sms/sent #checkhandler=/usr/local/bin/multiplerecipient logfile = /var/log/smsd.log loglevel = 7 delaytime = 20 errorsleeptime = 10 blocktime = 3600 autosplit = 3 [GSM1] #init = ATE0+CPMS="SM"+CNMI=2,0,0,2,1 device = /dev/ttyACM0 incoming = yes #You don't need a PIN for mobile phones pin = 1234 mode = new baudrate = 19200 rtscts = yes cs_convert = yes report = no memory_start = 1

Ill answer to myself, i changed Nokia CS-15 to nokia mobile phone and everything worked like charm after that without any usb disconnects.
So CS-15 is incompatible with sms tools at least if OS is ubuntu 9.04 or 10.04.

It looks like hardware problem.

1. test CS-15 with different computer;
2. EMI from modem can affect your computer; try usb extender;
3. try connect CS-15 via powered USB hub.
