USB modem sony ericsson md300 not recognized in 411uahr

We have a new 411uahr and trying to connect to a 3g network via a sony ericsson usb modem, but the board will not recognize the modem, either in resources or in ports,
and the modem is supported by mikrotik
do we need to install some drivers?
what can we do?
thank´s in advanced

Any device plugged in 411uahr USB port is not powered via USB port - external power adapter is required.

how are you supposed to power a usb stick?
