Hi,
I have a problem with USB devices on my guest OS (Windows 7 64bits).
It says that the driver failed to install and displays "The device cannot start. (Code 10)" in Device Manager.
I've installed the VirtualBox extensions and guest additions.
I've rebooted both Guest and Host and it still doesn't work.
Is there something I could try ?
Update: Got it. I had to enable USB 2.0 in the virtual machine configuration. It was not enabled by default as I created the machine before installing virtualbox extensions.
