There's more to it than what you have done so far. You must uncomment four lines in that file, as you have already done:
Uncomment 42-45 lines starting with #mkdir -p /dev/bus/usb/.usbfs
gksudo gedit /etc/init.d/mountdevsubfs.sh
You may wish to add this as a line in your fstab file:
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb
Some have found this necessary for USB drives, likely a race issue.
usbfs /proc/bus/usb usbfs auto 0 0
Reboot and you should see your USB devices in VMware's Removable Devices menu.
