My goal is to access thumb drives and MP3 players from a VM. I have VB 5.1.14 installed on a Windows 10 host, running a Windows 7 Pro guest VM. I have the 5.1.14 Guest Additions installed on the VM, and I have the latest extension pack installed on the host. When I go into VirtualBox Manager, and open USB Settings for my VM, the settings are disabled/greyed out. USB is selected, and the version 1.1 radio button is checked. I assume I need EHCI or xHCI selected to be able to access USB 2.0 or USB 3.0 devices. In the VM, if I open 'Devices' - 'USB' after plugging in a thumb drive, there are two additional entries ("Unknown device" and "Generic USB2.0-..."), but clicking either of them doesn't access the USB stick. (It makes a couple of sounds, but they don't meaning anything to me.) How can I enable the disabled settings? What do I need to do to use my USB devices from my VM?
Thank you.
