Comment 45 for bug 565058

I am on Ubuntu 10.10 using a Huawei E160 USB modem and experience the same bug. (Note that in lsusb the E160 is shown as 12d1:1003 and is named E220/E270, so apparently it is technically identical to the E220.)

If I have my device plugged in when booting, it shows up in the network manager applet ready for use.
If I plug it in only after booting, I have to manually issue the 'modprobe option' command to get it working.

I have both usb-modeswitch and usb-modeswitch-data installed, but I did not see any effect on said behavior with manually running usb-modeswitch.

What I have found out respectively can confirm so far:
If I have the device plugged in at boot time, among others the modules usb_storage, option, usb_wwan and usbserial are loaded.
If I plug in the device later, only the usb_storage module gets loaded, any only with the command "modprobe option" the other three modules (option, usb_wwan and usbserial) get loaded, to achieve the same list of loaded modules as when booting with the device already connected.

If it helps I can attach all data similar to those Bartosz has sent or any other system output if requested.
