I rebooted my machine the other night and when it came back on, my Logitech EX 100 mouse and keyboard were non-functional.
They (the keyboard, at least) work in bios, when the adapter is plugged into my laptop, both devices work flawlessly, just on my main machine, it's a no-go. This is maddening.
I downloaded the newest Setpoint version from Logitech to no avail, I've disabled and uninstalled all of these usb devices in my device manager, and tried the adapter in every usb port (there are 12) on my motherboard. All other usb devices work fine. A rather deep googling hasn't come up with much of help.
Can you try to do a system restore from safe mode? Sometimes it fails if you do it from the normal desktop, but if you boot into safe mode, it might work correctly. If it gave you an error telling you there is not enough room on your SSD, then this won't work, but it's worth a shot. In safe mode, does your mouse and keyboard work? To boot into safe mode, turn on the computer and immediately start pressing the 'F8' key repeatedly and choose safe mode.
Also, you can try to completely delete Logitech Setpoint from your computer, then plug in the mouse and keyboard and let them install themselves, without installing Setpoint.
There's no failing on the restore point bit, there are no longer any restore points, despite there being more than ample space on the boot drive now. In safe mode, the KB and mouse are still not working, and removing SetPoint did nothing, i'm sad to report.
The SSD isn't huge, so I've pretty much made do with all of my programs on other drives; reinstalling windows isn't so much of an issue any more, but i don't even want to contemplate that til i know that will 100% solve the problem and nothing else will.
I have a similar problem. My Logitech M705 mouse is no longer working with my computer. The first one I bought had some technical difficulties inside the mouse, so I replaced it. The new one is not even recognized by the computer as being plugged in. I uninstalled and reinstalled SetPoint, as well as any related drivers. I also changed the batteries in the mouse and verified that they are aligned correctly (the green light on top is on). I tested the mouse on my dad's laptop (a Dell Latitude with Windows Vista), and it works fine, but Windows 7 will still not recognize it. This has been a problem for several months, and I do not have restore points that far back (nor can I afford to lose that much data). Does anyone know of a program that might be messing me up, or a software patch I should get, or anything?
Also, I tried my dad's Microsoft mouse on my Windows 7 computer, and that worked fine.
