μC  USB  μC advice please!
What you are looking for is USB Host, sometimes called USB OTG.
Not all microcontrollers can do this, but you should be able to find some.

That is only the hardware side though, you will also need software. For example, what device classes does the radio use? (it can have multiple) Does it enumerate as virtual serial port, or does it use custom drivers?

If you know this, you can get onto host software. Mbed has a library.
