I have a Logitech MX1000 Laser Mouse which was working without a hiccup until I uninstalled the nVIDIA display drivers, put in an XFX 7800GT and installed the 81.85 drivers. I re-booted, got to the WinXP log-in screen and noticed the mouse no longer worked. I unplugged it from the PS2 port, tried all the USB ports and nothing. For the heck of it, I grabbed my trusty MS Optical mouse and plugged that into the PS2 and USB ports with complete success.
I d/l'ed the latest Logitech "SetPoint" software and installed that and still, nothing. When I look in 'Device Manager', the MX1000 doesn't show up at all and there's not even the "!" next to the "Mice and Other Pointing Devices". In fact, the "Mice" category doesn't even show up! However, when I plug in the MS Optical, IT shows up.
Is the mouse fried or does WinXP just no longer like the thing? And why would this happen as a result of installing display drivers and replacing a video card?? An IRQ conflict maybe?
