VMware Fusion and Lion USB not working

I upgraded my Mac to OS X 10.7 Lion the other day and found that USB devices no longer worked.

They appeared in device manager saying they could not start.

I found the following fix on the VMware forums :

You can check if you have non standard permissions by opening a terminal and running:

ls -ld /

You should see output like this:

drwxr-xr-x  53 root  wheel  1870 Aug  4 12:43 /

If the permissions are different than above you can reset them using the following steps (for Fusion 3.1.3):

Shutdown Fusion.

In a terminal (/Applications/Utilities/Terminal.app)

sudo -s
chown root:wheel /
chmod 755 /

Start Fusion and try connecting a USB device.
