There is an input driver "hook" that I have tested, and it is helping other people with older items that the manufactures will not support.
It is called Xmousebuttoncontrol
This will provide for 3, 4, 5 button mouses using the standard compatibility or for Microsoft Intellipoint mouse drivers, plus an array of other things like per program configurations, and hotkeys and all.
Then Windows 7 might drop-out the low level hook if it delays for too long, or if some other thing causes a delay, so there is this registry location.
At this location the timeout for hooks (general) can be altered.
IMPORTANT: The number that is there is not tested by me. It will have to be tested and set as you need it. The number should be considered a placeholder or example.
Because it is NOT a Driver, this is NOT an answer.
I think there are some creative crossing up by using other "new" drivers and getting them to work with Old stuff, but I have not got that far yet.
