USB Port Oddities
As part of my on-going Windows 10 problems, I discovered a USB-port related one that I do not understand. It started when I plugged a USB key into the upper port on the front of the computer, which was not recognized, so I tried two open ports on the back of the case, with the same result.
I took the key to my wife's computer, plugged it, and it was instantly recognized. I went back to my computer, and removed the wireless mouse transmitter from the lower port on the front, plugged it into the upper port, and had no mouse.
Final step was to plug a non-wireless mouse into the lower front port, the one that works for my wireless mouse; instead of loading the driver, nothing happened, so I replaced the transmitter, and the wireless mouse started working.
This is completely beyond my ken. I do know that the non-wireless mouse worked under Windows 7 when plugged in to either front port, but I don't recall if I had tried it with Windows 10 when I was having a problem with a new wireless mouse. USB keyboard, USB charging cable for wireless mouse, and USB 3 external hard drive all work.
Control Panel/Device Manager shows all USB devices working properly, but something is clearly amiss. Any ideas as to what and how to fix this collection of oddities?
