Prevent or block USB storage devices installation except USB mouse and USB keyboard

Hi ,

I want to ask , how to restrict USB storage devices installation or to block ?  Actually, I visited a company there owner asked me how to disabled USB storage devices. I adviced her to disable it from regitry via USBSTOR key or from group policy. She told me I knew this method already and searched on google alot already. But the problem is that when somebody came with new modern USB storage device of any other new vender then these setting can not prevent or block any new USB strorage devices because of there drivers are newer.

I have also seen a option of "deny write/execute access removable device" in group policy.  Is that good for all USB devices.

Operating systems are: windows 7 premium/pro/home , Windows Vista pro/home/prem and XP. If you know any good third party software then let me know and please give your any suggestion. I hope you understand me if you wany to know any more then you can ask me.

Thanks and regards
