wojtekhyla Posted October 31, 2018 Share Posted October 31, 2018 Hi, Here is my efi folder: EFI_config_e5440_20181031.zip After connecting the USB 3.0 device it gets the message "USB action requires power, connect" USB "to the USB port on this Mac". USB 2.0 devices work well. I can not cope with running an SD card reader. Please help Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 31, 2018 Administrators Share Posted October 31, 2018 Please post an IOReg output so that we identify the SD card reader. Which USB3.0 device prompts for power? Maybe the device requires more current/power than the USB3 port can provide... This would then require an external power or a dual USB3 connection to draw more power. Quite typical with some external HDDs. Link to comment Share on other sites More sharing options...

Administrators Bronxteck Posted October 31, 2018 Administrators Share Posted October 31, 2018 then double check your kexts and your configs. compare the working USB one to the non working one and correct it. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 31, 2018 Administrators Share Posted October 31, 2018 You don't need the GenericUSBXHCI kext. Your USB3 XHC controller will be supported OOB with your existing Darwin injection in DSDT. If you want to enjoy USB2.0/USB3.0 muxing, install Rehabman's FakePCIID ° FakePCIID_XHCIMux kexts. Then, you should be sorted. I also noticed that, in your Clover config, you've setup USB as follows: I'd tick Inject + High Current options if I were you..
