Is usb ethernet still being developed ?

Hi

I'd like to connect a 3G radio which supports CDC ECM

Is USBEthernet a good choice?

Do you think I'll have to make changes?

Thanks

John

Hi John,

USBEthernet is not supposed to work with modem, you are perhaps looking for a Host module to support USB Serial, or a host-side support for CDC-ECM, which is not in mbed AFAIK.

USBEthernet is to connect the mbed board (as a guest) to a USB Host and realize a CDC_ECM point-to-point connection, such as https://en.wikipedia.org/wiki/Ethernet_over_USB

Thanks,

I think my use of the word modem was incorrect - I've changed it to radio in my question.

You are correct - I'm looking to use a host platform which has a USB host port .Then connect the radio to the platform USB host port. The radio already supports USB ECM in the same way that USB ECM ethernet hardware works

I am hoping to use the radio with the standard arm mbed IP stack in the same way as USB ECM ethernet hardware - is this possible? -any direction on where to start?
