Jonas,
Thanks for the input.
I'm now looking at the F3307. �lsmod indicates that cdc_ether has been loaded, and ifconfig -a shows a usb1 network interface. �Yet, still the device property of the modem as reported by modem-manager is ttyACM0. (See attached).
I also see a warning from modem-manager that could be related:

I have also attached a file with debug messages.
In terms of priority, we are trying to make sure that the F3307 works in the next two weeks, though ideally this week. �I will be spending time looking at the issue. �Any help you can provide is appreciated -- but I understand that I didn't give you any lead time.

Jason,
We need some more time to be able to test and look at the current code, we are currently �somehow loaded with finishing a delivery.
I'll do my best to find some time so we can test and look into the latest code, do you have any deadline when you must have this ready?
Your expectation is correct, the device name should be usb[x]/wwan[x]. The ttyACM[x] is the name of the modem port. For the F3307, it could be that the VID/PID is missing in flimflam, for F55 you also need the cdc_ncm driver.
Thanks,
Jonas

Subject: Trouble with F5521 and F3307
Jonas,
I know we skipped out Monday meeting this week, but it seems like interest in the Ericsson modems is picking up again, and to ensure that things are moving in the right direction I started testing our F3307 and F5521 modules again. �We are now actively working on the GSM support in Chrome OS and it would be great to see the Ericsson modems fully supported.
I ran into some problems though, as highlighted below.
* � � � A warning from modem manager about net/usb1. �This then causes our connection manager (flimflam) to fail because ttyACM2 is not the network device (usb1).
* � � � I am unable to enable the device (manually)
* � � � Power cycling the device does eventually allow me to enable the device and get status output from it. �The device registers on the network, but it still has the wrong "device": ttyACM0 not usb1
We are now running very close to the upstream modem manager. �Do you know are the F3307 and F5521 working for you on Chrome OS? �Do you have any hints to offer in debugging this problem? �Is my expectation that the device should be "usb1" not "ttyACM0" correct?
Thanks,
