I can't see any usb-modeswitch problem but your ZTE dongle does repeatedly fall off the usb bus and moment later arriving again with its initial id 19d2:1595 which usb_modeswitch immediately switches to 19d2:1592. This sequence is repeated through the whole log session:
09:49:38 19d2:1595 09:49:41 modeswitch 09:50:17 19d2:1592 09:51:07 19d2:1595 09:51:07 modeswitch 09:51:08 19d2:1592 09:51:56 19d2:1595 09:51:57 modeswitch 09:51:57 19d2:1592 09:52:51 19d2:1595 09:52:52 modeswitch 09:52:53 19d2:1592 The most likely reason for a device to fall off the usb bus is that it draws more current than what the usb port can deliver. A faulty usb controller or abad usb cable can also cause this problem but power problem is the most likely. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1903331 Title: usb-modeswitch 2.6.1-1ubuntu2 is very buggy on Ubuntu 20.10 Status in usb-modeswitch package in Ubuntu: Incomplete Bug description: Hi, I recently allowed groovy-proposed package install of usb-modeswitch 2.6.1-1ubuntu2, because the default one which came with the system was useless. * What you expected to happen: My USB drive should be detected as mobile broadband connection faster as possible without any unpleasant inconvenience after boot stage. * What happened instead: It takes up to 15-25 mins to my USB Drive be recognized as USB mass and be truly ready for mobile broadband connection. Until then, any tries to connect to internet even if it appears to be ready on system menu or network settings - mobile broadband - results in failure. When I try to connect in that period, the USB mass is ejected and prepared for ready mode automatically after few secs beyond every time. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu50 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.10 InstallationDate: Installed on 2020-11-05 (1 days ago) InstallationMedia: Ubuntu 20.10 "Groovy Gorilla" - Release amd64 (20201022) Package: usb-modeswitch 2.6.1-1ubuntu2 [origin: unknown] PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 5.8.0-26.27-generic 5.8.14 Tags: groovy third-party-packages Uname: Linux 5.8.0-26-generic x86_64 UnreportableReason: This does not seem to be an official Ubuntu package.
