-> Unplug all the USB devices connected to the computer ( Less keyboard + mouse ) please use corded kbd+mouse if
possible rather than a cordless device.
-> Go to device manager
-> Delete all the USB HOST CONTROLLER -- All of them --
-> The host controller might reinstall them itslef, let the computer handle the reinstallation
-> If the computer does not reinstall the host controllers, trigger the detection using the DM function " Scan for
new hardware " ( The computer with magnifier icon )
-> Once reinstalled, clean boot
-> Reinstall the software if available and/or plug the hardware when needed.
-> Should work.
This TB delete the usb ports " memory " means if a device as been previously flagged with error, it will redetect
the device without the flag, unless there is some serious issue with the hardware/OS
If after this the issue persist, then I suggest you to call Logitech support to issue a replacement, hardware
failures are covered by warranty terms
Thanks and have a nice day !
