@ Saurabh Sharma Your E3531s is a new version, its 3 serial interfaces should be supported by the option.ko driver in Mint17 but the direct ethernet interface is not, it was added to net drivers two weeks ago so will be supported from kernel 3.17.
Please do: cat /proc/bus/usb/devices and verify that option driver has bound to 3 interfaces. If it has then you should be able to use the dongle in ppp dialup modem mode until you get an updated kernel with driver support for the net interface If option driver hasn't bound then you'll have to load it manually: modprobe usb_wwan modprobe option -- 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/1308895 Title: Please merge usb-modeswitch from Debian unstable - Huawei E3531 does not automatically switches to modem mode (no udev rules for this modem in Ubuntu's /lib/udev/rules.d) Status in “usb-modeswitch” package in Ubuntu: Confirmed Bug description: The operating system does not see the modem maybe because usb- modeswitch not automatically switches the device mode the modem.
