Hmm, what I can see there is a device which either does not need any switching or was switched correctly. 1410:7001 is a known TARGET mode ID in usb_modeswitch.
In the latter case, there should have been a log file from usb_modeswitch in /var/log though. What I find suspicious are these repeating lines in your syslog: ... usb 1-4: reset high speed USB device using ehci_hcd and address 3 ... I know that some of these on-device install storages are quirky, returning wrong "mode sense" values and otherwise behaving badly. Try this (as root or with "sudo") to prevent the resetting: # echo "1" > /sys/bus/usb/devices/1-4/avoid_reset_quirk Check the device address, it may have changed; the "1-4" is from your log. Also, there is no sign that the "option" driver is binding to the device, even if the device ID is known to it. So you are lacking the serial ports for using the device (should be ttyUSBx). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/750362 Title: [novatel mifi 2372] device is not recognized -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
