Comment 9 for bug 637948

Please make sure you give us the listing of lsusb *after* usb-modeswitch has run as well as immediately after plugging in the device, so we can check if there's just a target device missing from the configuration.

Also, please attach a copy of /var/log/syslog so we can see what happens at the network-manager level if the device has been switched. Note that for some devices you need to wait up to 2 minutes before the device is ready to be used.
