Hi, thanks in advance for any help.

I have a hauwei E5332 which i belive is basically an E5331 with ability to mount external antenna, plugging it in with usb-modeswitch installed happily turns it into a mass storage device and a usb modem, however im fairly sure it also has a ethernet over usb function aswell which i would like to gain access to. Referencing this post http://www.draisberghof.de/usb_modeswit ... f=3&t=1322 I've had a tinker around with usb-modeswitch trying to get it to the id 12d1:1c1f but havent had any luck it always ends up in 12d1:1506

I've disabled automatic switching so i can tinker, and I've put the output from lsusb and dmesg below, any help would be much appreciated.



Here's the lsusb output prior to modeswitch

You can not choose which target id the dongle gets after switching, that is decided by the dongles internal firmware which varies depending on which market or mobile provider it is intended for,
12d1:1506 is as good as 12d1:1c1f.

Your lsusb listing does not show any modem interface but a direct ethernet network interface so if it is working for you then I'm quite sure that you are using the ethernet interface.
I have actually never seen any of the Huawei MiFi devices having a dial-up modem interface, almost all of them have a cdc_ncm type ethernet interface and a few of them have a cdc_ecm type interface.

Unfortunately, its coming up as a usb mobile broadband modem in network manager, it definately doesn't appear on the list of network interfaces (ifconfig), and the devices web management interface is unavaiable because no ip has been assigned to the usb connected computer as its not been seen as an ethernet over usb connection.

I might have to retract my statement about it working happily, it appeared to be, it appeared as a mobile broadband device with the connection option for the service operator automatically discovered but on closer inspection it attempts to connect to the then fails. However if i access the device via wifi from another computer (at the same time as its connected via usb to the first computer) I have a working net connection and access to the devices web admin interface.

I went and plugged it into a windows 7 system and it came up instantly as a network connection and got an ip assigned by the devices dhcp in seconds. even ran usbsniff on all the hauwei devices that appear on plugin, but the files a bit large 7meg-ish to wade through when im not entirely sure what im looking for.

Time to do a bit more digging

If you get a working net connection on the usb connected computer then you have the cdc_ncm drivers and it must be a matter of NetworkManager not being able to initiate the connection with the right AT cmds.
You need a quite recent kernel and the latest NetworkManager in order for cdc_ncm devices to work.
