ChypherFox Posted June 10, 2022 Share Posted June 10, 2022 Hello! Please help with usb Have this setupAMD FX 8320 ASUS SABERTOOTH 990FX R2.0 AMD RX580 MAC OS Big Sur OpenCore as bootloader Have trouble with usb portsUSB 3.0 NO WORKING ALLUSB 2.0 working in mode USB 1.1 and as a result, the usb speed is small, the installation took a very long time, also because of this, the focusrite USB sound card does not work, since usb 1.1 does not seem to be enough for it (seen in device manager, but wont seen in focustire utility and don't give sound) does anyone have a kext for USB injection? This motherboard has an asmedia ASM1142 chip Also i clipped EFI a little lower EFI.zip Quote Link to comment https://www.insanelymac.com/forum/topic/352065-need-to-inject-usb-30-ports-on-big-sur/ Share on other sites More sharing options...
ChypherFox Posted June 11, 2022 Author Share Posted June 11, 2022 On 6/10/2022 at 9:00 PM, Hervé said: USB2.0 ports working only in slow UHCI mode is typical of incorrect BIOS settings: legacy/full speed vs high speed; check it out. There was a similar matter posted here very recently. Re: USB3.0, it could be that the controller is not supported by Big Sur or that you ned to add one of those XHCIUnsupported or GenericUSBXHCI kexts; you'll have to experiment. You may find this old thread useful on the matter (support for those USB3.0 controllers stopped at Catalina, unsupported in Big Sur). This did not help and fun fact I find some man with this motherboard and he injected usb and all works fine but when i launch EFI from him on my motherboard with same settings and bios version, usb ports didn't work Quote Link to comment https://www.insanelymac.com/forum/topic/352065-need-to-inject-usb-30-ports-on-big-sur/#findComment-2784765 Share on other sites More sharing options...

LockDown Posted June 29, 2022 Share Posted June 29, 2022 (edited) 4-Port USB3.0 PCIE Card is considered to be part of the 15 port limit? If so, i will only have 11 remaining ports to be mapped?

And for every hub. 2 Quote Link to comment https://www.insanelymac.com/forum/topic/352065-need-to-inject-usb-30-ports-on-big-sur/#findComment-2787520 Share on other sites More sharing options...
