The problem lies in the fact that my phone's ID (from
lsusb
) is:Bus 001 Device 007: ID 05c6:f000 Qualcomm, Inc.
which unfortunately is the same ID with some random USB 3G modem. D'oh!
Rather than dealing with usb_modeswitch I'm unfamiliar of, I'd just remove the package. who needs 3G modem from boxes directly connected within internal AS circle anyway?
# apt-get remove usb_modeswitch
Now the pain is gone.
