hoaug Posted April 9, 2023 Share Posted April 9, 2023 hi everyone, I started installing macOS Ventura 13.3 on my PC and it was done after a few difficult days. My PC: CPU: E5-2696 v3 MAIN: HUANANZHI X99-F8 GPU: RX580 RAM: 64GB SSD: SN550 I thought it was complete but no. when i plug in my iphone i get an error: the iphone automatically disconnects, it keeps reconnecting and then disconnects from the computer again until i unplug it from the usb port. I have tried the following cases: - Map USB : I tried again and again - mapped the USB using USBToolbox + USBToolbox.kext (I'm pretty sure I've mapped my USB ports correctly and 100% correctly) - Bios Settings - USB Configuration: + Legacy USB Support = Enabled + XHCI-Handoff = Enabled + EHCI-Handoff = Enabled - Change the cable to plug the iphone with the computer (always USB -> Lightning) - Change iphone device * There is a strange thing here is that on the Windows side everything is normal. So I tried installing Parallels to emulate windows and oh my gosh, my iphone plugged in to my computer was fine. how strange. - My web cam has the same problem. After recording for a while, it will automatically disconnect - It seems that the problem only occurs with the device that needs power from the USB port to use it. Someone please give me a solution, I've been stuck for days but can't find the solution, I need to fix that error because I'm an iOS App Code Dev. Is it due to the main error?. Please help me, thank you very much. below is my EFI. ( EFI works flawlessly.except that connecting iphone to computer via usb port does not work) - I use FakeSMC.kext and its kexts because VirtualSMC.kext doesn't work on my machine (it gives me an unbootable error) EFI.zip Quote Link to comment https://www.insanelymac.com/forum/topic/356320-cant-connect-iphone-using-usb-port-huananzhi-x99-f8-e5-2696v3/ Share on other sites More sharing options...
Slice Posted April 9, 2023 Share Posted April 9, 2023 First of all look here Installing Monterey/Big Sur on all X79 Motherboard like Huananzhi, Chinese, Gigabyte, Asus etc and PowerManagement I think you may find here answers on your question.

Slice Posted April 10, 2023 Share Posted April 10, 2023 There is another similar solution [SUCCESS] HUANANZHI X79-ZD3 + Xeon E5-2689 [Mojave 10.14.6] [Big Sur 11.2.3] [Monterey 12.0.1] You have to find a solution for USB ports on such motherboards and apply to your one.
