Here's my current setup that works with E3276 on MR3020:
Modem firmware - 21.132.01.00.000
ROOter firmware - Huntsman 2013-11-10 Red
Router Power - 4-ports USB Charger (Connected main router cable to 2.0A and secondary router cable to 1.0A)
AT Command used - AT^SETPORT=”A1,A2;10,12,13,16″ (note that this will disable the virtual CD and microSD card reader, i prefer this as I don't like the annoying prompt every time I plug E3276 into my laptop)
For those that can detect but can't dial, make sure that at ROOter > Modem > Information > Device Debug Information, you have the modem component detected:

If you're just getting the Linux hub (I experienced this on my WR710N and MR3420V1), you may try the following:
- Unplug the E3276, wait for one minute and plug back in
or
- Go to ROOter > Modem > Connection and switch USB Power (if supported) to OFF, save it. Wait for 1 minute or so before switching it back to ON and save.
I prefer the 2nd method since I put them outside the balcony.
