When connected via cable, it'd do the same kinda intervals as the above, but instead would have all three bar lights turned on, green, with the third bar flashing, as if it were charging.


Then 5-10 minutes later, it'd do it again. When connected via lightspeed, it'd flash (on the 3 DPI / Battery light bars, a single bar would flash) back and forth between green and red for a moment or two, at about 1second intervals, and then all lights would shut off. Now you should have got everything and should be able to turn it on.I know I'm 2 years late to this party, but thank you for this comment.saved my mouse today, and hopefully others stumble upon this.For each Logitech one run the command pnputil /delete-driver oem.inf Expand each one and you should see some items like "oem55.inf". Go to where you toggle the memory integrity on/off in Windows and you should see a link some to some more details.Open the command prompt as an administrator.As an alternative to using device manager I think you can also use Nirsoft's USBDeview also. For me, I had to delete "USB composite device", "HID Mouse", "HID Keyboard" and a camera. After you identified these then delete the the items. Plug in each item one at a time and note what goes from the hidden faded state to the normal state. Open the device manager and look under Universal Serial Bus controllers, Mice, and keyboards(even if you have a mouse). right click on all items that are Logitech and Uninstall (if preempted to uninstall the drivers click yes).go to device manager -> view(top Menu) -> show hidden devices.unplug all Logitech peripherals (cameras/ keyboards/ mouse / etc.
