This question I toss for a long time, has been unable to solve, later in the Oracle forum to see a reply, said he is the same problem, then the AMD USB Filterdriver to remove the OK, according to his method to remove the driver, it can load normally.

On another computer also has the same problem, after inspection, the above installed Moto Mobile phone driver, as long as the driver removed, you can normally load USB devices.

If you add the filter in the settings, there is no prompt to discover VirtualBox USB device, it is likely to have a connection, or you install other drivers, shielded USB drive, so that VirtualBox can not capture the USB, so the guest can not be used to properly use USB.

Manually uninstalling AMD USB Filter driver driver win7x64 The Catalyst Install manager unexpectedly said that I did not install any driver.

So look at AMD's documentation and find a way to uninstall it manually.

Installing and uninstalling the Driver

These instructions explain how to install/uninstall the USB filter driver:

Note:for driver installation, you must log in as Administrator or has administrator rights for your domain login.

The driver can installed either by running the CIM installer or by right clicking the INF file and selecting Install.
1. Install/uninstall Using INF File



To install

1. Right-click on the Usbfilter.inf file, and then select Install.

2. When installation are complete, reboot the computer.
Note:using the above installation method would cause the Device Manger to show Usbfilter.sys to be unsigned. This is Device Manger issue and the driver are WHQL signed. If The driver is not WHQL signed, Windows would give a warning while installing the driver.

To uninstall

1. Open the registry and scroll down to:

hklm\system\ccs\control\class\{36fc9e60-c465-11cf-8056-444553540000}

2. Remove Usbfilter from UpperFilter.

3. Open the Hklm\system\ccs\services registry and delete the Usbfilter key.

4. Delete Usbfilter.sys from:

\%system32%\drivers

5. Reboot the computer.
It seems that only AMD USB Filter driver supports this type of uninstallation, and only this has a virtual machine problem.
