Hello

I infall my Virtual Box on OSX 10.9 Mack book pro and Install Win 7 as guest , I setup the USB port according to my manufacture USB , when I log on to my Guest Win 7 I keep receive error that the driver failed to install, I have try all possible way to rectified that but no luck here is what I have done so far

1- The USB is working fine on another Windows based PC
2- From Virtual Guest Windows 7 guest I delete the driver from Device manager and reboot come back same error
3- I have Windows full update to the latest version NO further windows update available
4- I use different USB port and still the same

I am running VirtualBox 4.3.8 I believe that the latest version

Under the VirtualBox setting and USB Tab the enable USB Controller is checked but in the man time is fray out I can't change any setting their and the Enable USB2.0(EHCI) Controller is not check and fray out as well - I already create the filter for my LEXAR Jump Drive and it is checked

Your help is appreciate what I am doing wrong to get my USB recognise by my Win 7 ?

Have you installed the VirtualBox 4.3.8 Oracle VM VirtualBox Extension Pack?

Does your Mac have USB 2 or USB 3 ports? USB 3 isn't supported in VirtualBox yet.

Thanks for your reply

I just install 4.3.8 do I have to get the Extension Pack?

My Mac running USB 3

Yes, you need to get the Extension Pack. It's on the same web page where you downloaded VirtualBox.

I got and my USB version 2 is working just fine

What I still have a problem with is my External Hard drive Westdigital 1TB I believe it is version 3 any idea why is not working with my Win 7 even after I install the extension Pack ?

Maybe it's because VirtualBox doesn't support USB 3 yet.

If you just need copy files to and from the external drive you can create shared folder the points to the drive. You just can't run apps from a shared folder as far as I know.

I am having a similar problem.

Mac host, Win7 guest. VB 4.3.10. VB Extension pack installed.

But I cannot get the USB 2.0 EHCI to enable. It remains grayed out and unchecked.

Are you trying to change the setting while the Win7 guest is running?
