Windows 7 HP Scanner Buttons To Pc not working?

[Fool Monkey]

Hi,

An HP M1522 NF all in one printer/scanner with fax capability running W7 32bit via USB.

I managed to get the HP software to install via the USB express install

method after deleting all the .inf, .sys, .dll HP related files, program files, progran data files,

app data files and removing HP registry entries.

But both of the scanner buttons on the unit still do not work?

Any ideas?

Your help is most appreciated.
