Comment 71 for bug 408555

New try: I used a new possibly faster that the USB stick, an SDHC as the LiveUSB (LL desktop beta 2)

Boot without modem, try ubuntu, all defaults (english, etc), modem attached, found, connected, 2nd try connected, 3rd try NO ACTION (at nm/mm).

Attached /var/log/daemon.log shows timing which can be compared with the 'human actions' described below:

sudo dmesg -c (to clear previous long dmesg)

23:40 modem attached
23:42 found at nm icon, new broadband connection, connected
(>>> terminal was open, mouse pointer disappeared, pressing ESC pointer came back)
browsing, time changed via internet to -3 hours
20:46 disconnected, modem removed
20:48 modem attached, found, green led was on, connected GPRS (ok), browse
20:52 modem found/changed to 3G, browsing all fine
20:54 disconnected, modem removed
20:55 modem attached again
>>> never appeared at nm icon, daemon.log froze at 20:56:40
21:00 modem removed
21:01 modem attached again
>>> no activity to daemon.log

daemon.log and dmesg copied to desktop (liveUSB has a minimum default persistent area)

21:0x >>> use all times classics!
sudo stop network-manager
sudo killall modem-manager
sudo pppd .... (long commaaaaaand), connected, launchpad.net, wrote this message (now time shows 21:22, actual is 00:22)

files attached for further debugging.

Regards,
George
