Hi, I have to interface with an internet stick for example Huawei E3372-153, is there a reference project?

    Almost certainly no.

    Is it a "well known" USB class, or vendor-specific? In the latter case, you are out of luck, in the former, it's still not very probable you could use it.

    Observe the descriptors (device, configuration) e.g. using lsusb after you connect the stick to a Linux machine.

    Sorry don't know about this specific stick, but usually they are multifunction CDC-ACM. One of interfaces even can be RNDIS.

    Some of these also do "identity switch" to expose USB storage with drivers, this is useless and can be ignored.

    Try to install this thing on a Linux machine or plug into compatible network router, and spy on it with USB sniffer.

    This is what the manufacturer had to say in this regard, verbatim:

    Thanks to you for your quick answers.

    Without a reference project, the way of optimizing the use of the internet key directly from the microprocessor becomes rather complex.

    So at the moment I give up this optimization and I'm going to use a Raspberry for it.

    Hello,

    I found the project "Pyrn3GModem" can it be useful in your opinion?
