[Bug 868034] Re: Huawei E220 can't connect on Ubuntu 11.10

 

I'm pleased to see the recent  progress being made by Mark and Aleksander (comments #102 - #104),  though  not happy that the priority still remains listed as "low".  
Meanwhile last night I managed to locate syslog file entries from both Maverick (ver 0.4) and from Ocelot (ver 0.5) for plugging in and trying to log-in on my Huawei E220,  and I'm attaching the Maverick one here.     I'll attach the Ocelot one for comparison in the next post.   These differ from  Mark's examples in that they show kernel entries as well as MM entries,  so perhaps there could be an additional clue there.
I'd love to try MM 0.4 in Ocelot and see what happens,   but sorry I don't feel  I'm quite up-to-speed enough myself to do that without risking an error that cuts me off completely!
