My Windows 7 system on Mac via Boot Camp isn't seeing any mice.
Mice were working fine up until yesterday, then suddenly stopped working for no apparent reason.
Move the mouse around, cursor stays in place.
I'm seeing this with my Razer "Naga" gaming mouse and also with a plain vanilla Microsoft USB mouse.
I tried the mice into a different machines and they worked.
I rebooted Windows 7 into safe mode.
In safe mode, the mice both work.
(BTW I updated the "Naga" driver from Razer's website, of course. I also updated the .Net framework as recommended by Razor support.)
UPDATE
Here pics to show what I'm seeing...
Device manager in normal mode
(Mice are not working)
Device manager in safe mode
(Mice ARE working)
What do I need to install or uninstall and from where to get these fine mice to work in normal mode?
Human Interface Devices
, if all is enabled there, you may try to disable and re-enable again?
