VirtualBox for your extension Ralink are not allowed to attach it. I came to know that the Ralink wireless utility or driver will not release it on the Virtual OS on the guest OS. I deleted the cut (make sure I first supported it) and rebooted. Now after VirtualBox OS (BT5R3 in my case) compiling it for the driver, after using the Monrobb RT5370 ST and blacklisting other RT2x00 and RT 2800, it sees it under LSUSB.
