Logitech keyboard inconsistent connectivity
I first mentioned a problem I had with my keyboard back in 2017 after I built my computer. I gave details in the following post:
Logitech keyboard inconsistent connectivity
What was different this time was that both my Logitech keyboard and mouse connection became more and more intermittent. Moving the Logitech USB dongle from the computer back panel to the computer front panel was only a temporary fix. When neither the keyboard or mouse would no longer work I decided it was time to finally find the cause of the problem. I unplugged the common Logitech USB dongle and replaced it with one from another dongle from a Logitech M325 mouse. Both the keyboard and mouse worked again. I then tried the problem Logitech USB dongle on another computer with a Logitech M325 mouse. The Logitech Bolt program couldn't even detect the dongle. I was finally able to verify that the original Logitech USB dongle was faulty. I bought a replacement Logitech USB dongle from Amazon.
Going back to the computer to test the new dongle I found out it was intermittent also. I remembered the problem I had back in 2017 and moved the dongle from the front panel USB 3.0 port to the back panel USB 2.0 port like they had been the last few years. Both the keyboard and mouse appear to work OK now.
Note that a wired keyboard and mouse were temporarily connected to the computer until the wireless keyboard/mouse were paired with the new dongle.
My main point with all this is I am still having intermittent problems with the keyboard/mouse combo when using one of the computer's USB 3.0 ports. A USB 2.0 ports works better. I am still not sure whether the problem is with the keyboard, motherboard, or some kind interference.
BTW, the computer also has a Tp-Link UB400 Bluetooth 4..0 USB dongle. Hopefully it is not interfering with the keyboard/mouse USB dongle.
