thank you for any suggestions.
Your extensions for Ralink are not allowing VirtualBox to attach to it. I found out that the Ralink wireless utility or the driver won't release it to the guest OS on VirtualBox. I deleted the kext (making sure I backed it up first) and rebooted. Now the VirtualBox guest OS (bt5 r3 in my case) sees it under lsusb after recompiling the driver for it, using modprobe rt5370sta, and blacklisting the other rt2x00 and rt2800.
