Rather than pasting just a single error line, please include the full debug log for running usb-modeswitch. You can do that by modifying /etc/usb_modeswitch.conf:
EnableLogging=1 And looking under /var/log/ for the log file written by usb-modeswitch after it has run. Having the full file means we know exactly what happens as usb- modeswitch tries to probe the device, it will be much easier to figure out what goes wrong and why. The "Could not read attribute" might not be fatal by itself; something else is likely making it impossible to figure out what type of device exactly it is and whether it is in the right mode. -- 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/1800794 Title: usb-modeswitch can't apply Configuration=0 to Snapdragon X12 LTE Status in usb-modeswitch package in Ubuntu: In Progress Bug description: Please refer to post of usb-modeswitch developer http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?f=4&t=2827 for complete issue description.
