The difference in having your mouse vs keyboard plugged into port 0 is a real noob trap. On this Haswell board in front of me, having the keyboard plugged into the first port and mouse in the second makes cursor movement seem a little more frictionless and faster, but it's also more floaty at the same time. An untrained nooblord like Skupples could mistake this as being a positive thing.

The difference in mouse movement between the two is probably the keyboard getting more priority than the mouse being in an earlier port and the mouse getting polls dropped or something so the cursor is more conducive to skip across the screen with less accuracy. And of course if you were using a USB3 controller with MSI mode instead of line based interrupts, neither port would feel correct and you'd have no idea w.t.f is going on or which one to use.

The two ehci USB2 controllers on Z87 have no reason to exist when used with Windows 8.1 or higher. Only in Windows 7 will it actually utilize those controllers at all. But Windows 7 is garbage with modern GPUs that use things like tile rendering (everything Maxwell and higher?) and need a fully 3d hardware accelerated desktop to not be junk. Windows 8.1 is the current master race gaming platform.

Makes sense actually. Since my via usb controller card feels better than motherboards native USB ports. Will try to force on-board usb's to line based when I get "on-shore" again

Been gaming on my intel USB 3.0 port for 5-6 years now zero issues, no difference between my usb 2.0 port on the rear I/O

Do you have any testing/proof/source?

The rules need to be amended. This forum has literally become astrology but with mice instead of star signs
