Hi, I am trying to use send sms using a gsm modem, but mine uses a usb port instead of a serial. Has anyone tried using a usb gsm modem. /media/uploads/cicklaus/modemusb-g10-big.jpg

If i'm remembering correctly, this has an USB to Serial converter inside, so you should be able to disassemble it and connect wires directly to serial port.

But beware, you could brick it, not my responsability if it gets bricked :D

Nope, it would need USB host to work. Then you could write a library for USB Host to GSM modem

Open the modem to check if it has a serial interface before threw usb interface.

I am working on a similar project. I am trying to use Huawei E169 (USB dongle) to send and receive SMS, however first the E169 (GSM modem) diver must be installed on your mbed then you can use AT command to send and receive SMS.

Please keep posting on the progress of your project.
