Your log shows many disconnects and reconnects, as Lars has noticed. If you have not unplugged your modem manually, then there is a problem with the USB connection. Note that it may also be driver-related, so does not happen on Windows.
In any case, usb_modeswitch is not the problem. The mode switch works every time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903331 Title: usb-modeswitch 2.6.1-1ubuntu2 is very buggy on Ubuntu 20.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/1903331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
