OnioTan Posted May 17, 2020 Share Posted May 17, 2020 (edited) Hello, I have problems with my USB ports on Z390 Aorus Master board.. Catalina 10.15.4 Mouse is laggy as hell. I have feeling that it does disconnect and comes back.. My ports are mapped with USBMap.command and maxed to 15. I found in IOREG this line where in real time i see my keyboard and AIO cooling goes red..what is causing that? Thanks Edited May 17, 2020 by OnioTan Link to comment https://www.insanelymac.com/forum/topic/343877-usb2-ports-dropping/ Share on other sites More sharing options...
