But the MU509 appears to provide a USB interface, and assuming it's the standard type of "vendor-specific USB serial interface" then what you want to do is try adding the USB IDs of the MU509 to the 'option' driver in the linux kernel, and then seeing if you can talk to the device over ttyUSBx using minicom or screen. Most WWAN devices that provide USB interfaces expose at least one AT-compatible serial port, and at the moment most Huawei UMTS/CDMA2000 devices are supported by the 'option' driver. The specific list you want is linux-usb.
