Hello,

I have a PC that is USB only and I am trying to use a USB to PS/2 adapter connected to a keyboard and mouse, it does not
 work correctly. The keyboard works well but the mouse has very limited functionality … moving it makes the mouse 
pointer move up or down only, left or right clicking moves the mouse 1mm to the right.

I am using the latest USB stack from Feb12.

I have used two different make of adapters with the same outcome.

The adapter works perfectly well under Windows XP and 7.

Thanks.
