baconeveryday Posted September 3, 2021 Share Posted September 3, 2021 Hi, I have a Dell 7040 (Skylake) desktop running OC 63 on Big Sur 11.0.1. Everything runs great with 2 DP monitors in 4K and have been on this configuration for the past 10mons. I'm trying to update to Big Sur 11.5.+ so first step was to update my OC to the latest (ie 0.7.2). I grab the latest kext, .efi, and .aml for my configuration and added to the OC 72 package. Update config.plist with specific settings for Dell 7040 (Skylake). Rechecked against the guide https://dortania.github.io/OpenCore-Install-Guide/config.plist/skylake.html#starting-point With all configurations updated to latest and using OC 72 - Dell boots and login screen comes up just like before but no USB enumeration or power. Tried plugging to all the usb ports and still nothing. What I've tried w/o success for each combination: Removed USBInjectAll.kext Removed USBInjectAll.kext and replaced with USBMap.kext. I configured USBMap to my USB ports. Used precompiled SSDT-EC-USBX-DESKTOP and PLUG. Re run SSDTTime and loaded PLUG and EC with USBX Any help is much appreciated. Thanks.

baconeveryday Posted September 4, 2021 Author Share Posted September 4, 2021 Hi MaLdOn Thanks for the suggestion. Following the instructions from, https://www.olarila.com/topic/9390-video-guide-usb-port-mapping-with-hackintool/, I created usbports.kext and verified USB ports mapped and working on OC63 running Big Sur 11.0.1. However when I update EFI to OC72 with the same usbports.kext running Big Sur 11.0.1, same issues - usb still fails. Thoughts? Thanks.

MaLd0n Posted September 4, 2021 Share Posted September 4, 2021 seems like a fine tune missing ssdt is a not a full solution. just solve basic things Link to comment https://www.insanelymac.com/forum/topic/348768-usb-issue-on-dell-7040-with-oc-072/#findComment-2765688 Share on other sites More sharing options...
baconeveryday Posted September 6, 2021 Author Share Posted September 6, 2021 What's strange is that it was working in OC63. So I'm going to trying OC67 and see. Not much more I can think of.

Allan Posted September 9, 2021 Share Posted September 9, 2021 Why are you using this old versions of OC? We have the 0.7.3 now 😬 Link to comment https://www.insanelymac.com/forum/topic/348768-usb-issue-on-dell-7040-with-oc-072/#findComment-2766032 Share on other sites More sharing options...
