[Bug 868034] Re: Huawei E220 and E1550 can't connect on Ubuntu 11.10
Hi Sleepy John and others, Since people still seem to have problems I thought I should chime in and share some of my experiences. I had problems with connecting my E220 on 11.10 oneiric using MM 0.5-1ubuntu1 after upgrading the modem firmware to 11.117.10.02.00. (Don't remember what firmware version I had before the upgrade.) I found a simple workaround that allowed me to connect reliably with ModemManager (detailed in duplicate bug #932824): Prevent MM to probe /dev/ttyUSB1 by starting the command 'cat /dev/ttyUSB1' before MM starts its probing. The updated version of MM currently in oneiric (which is supposed to fix this bug?), 0.5-1ubuntu1.1, does not work for me, but my workaround still works. To test if you have the same problem as I have, you can try the following: - Make sure the modem is physically disconnected. - Open a terminal and run the command 'while true; do cat /dev/ttyUSB1; sleep 1; done' (Before the modem is connected you will see messages like 'cat: /dev/ttyUSB1: No such file or directory' once every second. After the modem is connected and initialized you will see messages from the modem, such as ^BOOT:59866241,0,0,0,6 ^MODE:5,5 ^RSSI:27 and others.) - Connect the modem to your computer. - Connect using modem manager as usual. Note: After ModemManager is done with its probing you can abort the cat /dev/ttyUSB1 command. If this workaround works for you, you might want to try the ports branch of ModemManager which Aleksander Morgado mentioned in comment #145 (with more info available in the comments before and after). I've been using the ports branch since February and it has been working perfectly all the time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/868034 Title: Huawei E220 and E1550 can't connect on Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/modemmanager/+bug/868034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 868034] Re: Huawei E220 and E1550 can't connect on Ubuntu 11.10
Hi Aleksander. I've had the same problem since I updated my Huawei E220 to firmware revision 11.117.10.02.00 and 11.313.02.00.01 as detailed in duplicate bug #932824 https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/932824/. Before firmware update (possibly with firmware 11.110.xx?) everything was working fine. I can confirm that the ports branch works for me.

[Bug 932824] [NEW] ModemManager hangs Huawei E220 Modem when probing ttyUSB1
Public bug reported: After upgrading the firmware on my Huawei E220 modem to 11.117.10.02.00 I can't connect using NetworkManager. Before the firmware upgrade it was connecting without problems. My manual pppd scripts still connect without problems. The problem seems to be that the modem hangs when /dev/ttyUSB1 is being probed by ModemManager. The device used to connect the modem is /dev/ttyUSB0. If I start the command 'cat /dev/ttyUSB1' in a terminal before ModemManager starts its probing everything works fine. It seems like the connection to /dev/ttyUSB1 is blocked by the cat command and the probing of ttyUSB1 fails. I've attached a log file of a failed connection with ModemManager started in debug mode: ModemManager Failure On E220 Connect Full (From modem attached).txt. I will also attach a log file of a successful connection (with 'cat /dev/ttyUSB1' running in a terminal).
