Is it possible to use 2 3G USB modems from different vendors simultaneously?
I am working on an embedded Linux based on the Vanilla kernel version 2.6.28
I am able to detect and use a single USB 3g modem
However I was requested to check whether it is possible to use 2 different USB 3g modems simultaneously? (Note that these modems might be completely different vendor, gsm/cdma etc)
I am currently using the usbserial module with specific vendor and product ID for the single modem. I do not see how I can add another modem with a different product/vendor?
(A small confession - I am a newbie with 3g modems so perhaps am missing something very fundamental...)
Any pointers (or negative answers) will be greatly appreciated :)
I doubt you can exactly. In no simple configuration can one use two modems at the same time.
You can easily allow two to be installed and let one work at a time, if it fails then you could swap over or it should do it automatically.
There may be an authentication issue too depends on service.
Thank you for your answer
Installing two different ones at the same time but connecting only to one is good enough.
But how can that be done?
A great amount of information about this version you have would be needed along with the types of modems requested.
In a very general sense one needs drivers and some way to configure the use of the hardware and some way to use some service along with authentication.
The problems is I do not know the modem types :( as we support quite a few types
For now I guess we will not support multiple modem types (at least until our next software version... )
