Public bug reported:
Binary package hint: modemmanager
I have both an internal 3G modem (on /dev/ttyACM0, ACM1 and ACM2), which
I don't intend to use, and an external dongle (on /dev/ttyUSB0 and
USB1). The external dongle shows correctly in the Network Manager dialog
as "Mobile Broadband".
Modem-manager logging shows (Extract):
** (modem-manager:3014): DEBUG: Added modem
/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-6
** (modem-manager:3014): DEBUG: Exported modem

I don't wish to use the Ericsson
(/org/freedesktop/ModemManager/Modems/0) but instead the Huawei
(/org/freedesktop/ModemManager/Modems/1).
However, when I try to connect, modem-manager tries to use /dev/ttyACM0
as shown by debug mode:
** Message: Modem /org/freedesktop/ModemManager/Modems/0: state changed
(disabled -> enabling)
** (modem-manager:3014): DEBUG: (ttyACM0): --> 'AT&F E0 V1 X4 &C1 +CMEE=1<CR>'

(enabling -> disabled)
That's not really surprising, since the internal modem is turned off
using the RFKILL physical switch.
