I noted the G1.Sniper Z87 was Rev1.1 earlier, so that's as good as it gets from a hardware revision perspective.Ouch, only one BIOS available for this board since 2014. Guess they got it right the first time in their minds Refer to pages 46-51 of your manual. What are you using for XHCI?If using Auto previously, try EnabledAlso what about USB DAC (page 51)? Change this on the off chance the hub on your monitor is powered. You'll need to F10, save and allow the system to boot. Now shut down gracefully. Turn off rocker on PSU. Wait a few minutes and attempt cold boot. Have you tested with only one device at a time? Try this and see what happens. Is there a beta BIOS available? Might be worth a look on tweaktown, etc. It might just be the hardware you are using together since you said another mouse and other USB hardware is working normally. ??
Yes. When I connect the USB HUB of the monitor to the frontal panel of my PC (which is connected to, IIRC, USB1 connector on the MoBo), it also works flawlessly. The only issue here is the rear panel, which I find... weird. If compatibility was the problem, it should also not work with the frontal panel, no?
