Partial sucess, sortta.
Swapped USB ports and the Logitech LCD display showed the clock but wasn't scrolling through the other functions. I think this may be because I had it set to show clock only though, I can't recall. Like I said, I don't use the LCD display.
Unfortunately the mouse doesn't work through the dedicated USB keyboard port.
And without the mouse working I couldn't really test the gaming macros.
It may be worth experimenting with a USB hub plugged straight into the black (mouse) port but I don't have a USB port here at the moment.
I'm wondering if both the keyboard and mouse were plugged into a USB hub, they'd both work as they should do and the KVM would still function normally?
I'm also wondering whether you'd lose the keyboard switching commands.
Sorry can't be of more help atm, but without a USB hub there's little I can do and besides, it's that chill time of evening, time for a little CoD4 online
I will return to this topic.
