I think I'm only removing the modules so they can be reloaded afterwards, i.e. to reset their state. At least I think it worked equally both with reloading option afterwards and without. Now, option is actually loaded when I connect; and, interestingly it's not at the top of lsmod output, and, as I realize now, my own initialization scripts are not even called anymore as it seems. I'm quite confused; on 2011-03-20 /lib/udev/rules.d/40-usb_modeswitch.rules was changed to a version that doesn't call my hook. I don't have any record that I did this myself, and don't remember anything about it, I can only conclude that some Debian package upgrade did it. Sigh. (Ok I know that /lib isn't /etc, but then why are those files in /lib? Or do /etc/udev/ files override those in /lib/udev?) It seems the option module is actually being used by network manager (directly or indirectly), since lsmod shows its use count going up to 2 when I'm connecting, and dropping back to 0 when I unplug the stick. option 12918 2 usb_wwan 6147 1 option usbserial 21120 7 option,usb_wwan > I suggest that you go back to the beginning, probably a clean, fresh install > of > Squeeze, stick the modem in and see what happens. Or a live cd, or, .. I've just booted from a current Ubuntu live image. The exact same thing happens once it connects: 20 seconds after connection is up it is being dropped again. (This happened 2 times.) The difference to my Debian setup is that about 4 further times I tried to up the connection, it didn't even enter up state; network manager would just show "connected", but the stick would still blink its LED instead of going to light it up constantly as it would when connected, then a couple seconds later network manager would say "disconnected"; after that no connection attempt succeeds, I unplug+replug the stick to try again. So it's just worse... > In Squeeze usbmodeswitch is standard. Yes, but it didn't work reliably in Ubuntu back when I tried a year ago, and not at all in Squeeze (testing back then), which led me to write my own switching scripts. When I tried it on the newer Ubuntu today, watching syslog and nm popup messages, it seems usbmode switching is reliable (and fast, in ~2 seconds), but as mentioned it then fails to connect at all in the majority of cases. Actually I think that's exactly what happened a year ago, and I probably just mis-concluded that usb mode switching wasn't reliable on Ubuntu, where in fact the switching itself seems to work fine, but somehow in about 2/3 of cases leaves it in a state that doesn't allow it to connect. How do you connect, using nm or something else? Well I'm also going to try a Debian live image, to confirm whether withoug my own scripts it works the same.
