I'm using the Logitech Vertical MX mouse and it works perfectly with one exception. If I use the CapsLock, ScrollLock, or NumLock buttons on my keyboard, the mouse becomes unresponsive and I have to power it down and back on to return it to operation. My setup is as follows:
Microsoft wired USB keyboard
Logitech Vertical MX mouse - connected via USB (not bluetooth or unifying receiver)
StarTech SV231DPDDUA2 KVM. I suspect the KVM is causing some trouble, but it would be nice if a work around could be found to enable full functionality as the mouse has been working for months flawlessly otherwise. Thank you for your time.
