G1 & Windows 7 no mount options

Hi all.

I have a G1 and a laptop running Windows 7. When I connected the phone to the lappy it would show 'mount USB' at the top of the phone an all would be well.

Now something has changed and the laptop shows an error message reading 'Unknown USB device' and the phone nonchalantly ignores the connection.

I have read a few posts but can't fine one that matches my problem and windows 7 have changes the way to access the control systems.

Please help. :D
