Neo_1979 Posted October 14, 2018 Share Posted October 14, 2018 Hello all, I have a problem with intel usb 3.0 ports. My laptop is a Dell Mobile Workstation M6700: cpu i7-3940xm extreme qm77 chipset 24gb ram ddr3 1600mhz nvidia quadro k3000m 2gb gdrr5 (I use this as my video card, optimus disabled in bios) 17,3" fullhd 1920x1080 ssd1 samsung 850 250gb (windows 10 os) ssd2 crucial mx300 525gb (downloads) ssd3 crucial mx300 750gb (caddy) (data and virtual machines) ssd4 lite-on msata 256gb (sierra mac os) 5 usb ports: 2 usb 2.0 (work flowlessly) 1 usb/eSata combo port (work flowlessly) 2 usb 3.0 intel ports (work as 2.0 ports) I can't figure it out to make 3.0 ports work at their full speed. Tried usbinjectall.kext and clover port limit patch for sierra (and rename ehc1 to eh01.....), nothing. Tried dsdt.amd patching with 7-series/8-series usb, nothing (this method worked for other 2 laptops) Tried fakepciid.kext + fakepciid_xhcimux.kext, nothing. They always work as 2.0 ports. In profiler there are 2 usb 2.0 controllers ehci. Not an XHCI is shown/found. Hope you can give me some advice to fix the problem. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted October 15, 2018 Administrators Share Posted October 15, 2018 In all likelyhood, your DSDT needs patching to support USB3. Check if and where you define OSYS according to "Darwin" OS detection, if at all. You need something like this. Best thing to do is what JaleLo suggested: post a zipped copy of your Clover folder (without the Themes subfolder). Or better, follow this.

Moderators Jake Lo Posted October 28, 2018 Moderators Share Posted October 28, 2018 Disable USB port limit, then use FBPatcher app to generate a USBPort.kext See here for more info https://www.insanelymac.com/forum/topic/335018-intel-fb-patcher-v157/ Link to comment Share on other sites More sharing options...
