IE. The initial fix that "enabled" usb-storage to work in 2.6.31.1 broke them causing them to get into a reset loop due to some issues with usb-storage. I've obtained a usbmon log from one of those users with a E620, I would appreciate if you could have a look as you are a lot better than I am at parsing those things :-) I attached it to the existing BZ http://bugzilla.kernel.org/show_bug.cgi?id=14355 . Of course it's always possible that a whole lot of users have been testing the wrong kernel and thus don't have the fix :-) But that might also show a different problem with those modems usb storage implementation. Cheers, Ben.
