Novatel 730L error
According to the guide here https://www.verizonwireless.com/dam/sup ... -guide.pdf
this is the command to change the mode but it is not working. Anything I can do?

Re: Novatel 730L error
Do you use the latest version of usb_modeswitch?

Re: Novatel 730L error
Hi. I have a similar problem with the same modem on Ubuntu 18.04, usb_modeswitch 2.5.2:
The modem keeps disconnecting with rndis_host module. But cdc_ether works fine. I want to switch the mode to use cdc_ether.
Any idea?
Thanks,
Vahid

Re: Novatel 730L error
Show me the verbose lsusb listing for 1410:9031, this is an usb id which I haven't seen before, do also show a complete usb_modeswitch log which you get by including the -W switch on the cmdline.vahid-dan wrote:Hi. I have a similar problem with the same modem on Ubuntu 18.04, usb_modeswitch 2.5.2:

Re: Novatel 730L error
Your USB730L has a different firmware from the one we previously knew about, there aren't any multiple configuration to select from in this one.vahid-dan wrote:Hi LOM!

You mentioned that you have problems when using rndis but that it works with cdc_ether something I don't understand since this firmware does not create any interfaces that cdc_ether can bind to directly.
It is also so that the linux rndis_host driver is a helper driver", it takes care of just a few rndis specific things but it depends on the cdc_ether driver which does almost all of the heavy job.
Re: Novatel 730L error
Thanks for your response. I have 3 identical computers with 3 identical USB 730L modems with the same operating system and modem firmware. One of them is using cdc_ether and the other two are using rndis. cdc_ether is quite stable but rndis keeps unregistering/registering the device and after a while just gives up. Here is the info for the other modem working with cdc_ether:LOM wrote:Your USB730L has a different firmware from the one we previously knew about, there aren't any multiple configuration to select from in this one.

Re: Novatel 730L error
I have no idea how you can do that but I don't think it involves usb_modeswitch.vahid-dan wrote: So my question is that how I can make my other two machines stop using rndis?

There has never been an entry for 1410:9031 in usb_modeswitch, your modems starts up in working mode without the need for any switching.
Your first lsusb listing shows interface 0 to be rndis with class/subclass/protocol attributes of 239/04/01 and with an Interface Association descriptor before interface 0 which your second listing doesn't have.
The interface attributes for interface 0 in the second listing is 02/06/00 ie cdc_ether.
If you are 100% sure that all 3 modems has the same firmware then I can only guess that the modem itself decides if it should show up as an rndis device or a cdc_ether device. What criteria it uses for the decision is unknown to me.
A guess is that Ubuntu 16.04 and 18.04 differ somewhere in the probing of the modem when it gets detected on the usb bus, could for instance be a difference in timing. I don't know and can't do much to help you, sorry!
The reason why many manufacturers have two configuration, usually selectable, is because they want to support two different architectures.
Apple can not speak any other net protocol than ether so needs an ether type interface , MS Windows could only speak rndis until Win8 when they also added the mbim protocol so it needs an rndis interface in order to cover both old and new Windows.
