chohsiao Posted June 6, 2021 Share Posted June 6, 2021 Hey guys. Today I upgraded Big Sur from 11.3 to 11.4 and the upgrade went smoothly. But when I entered the system, the wireless key and mouse could not work, which was caused by the unrecognized USB2.0 port when I checked. I connected to the system using VNC and found in Hackintool that all the USB2.0 ports were not working,USB3.0 works at 5 Gbps. I followed the instructions to disable XHCIPortLimit. All ports work, but USB flash drives on USB 3.0 ports only work in 480 Mbps mode. I tried to customize the ports through Hackintool, but after customization, only USB2.0 will work. I can find many HS ports in Hackintool, but only one SS port. Other USB 3.0 ports do not recognize both 2.0 and 3.0 devices. How should I solve this problem? Thank you.
