zefie Posted October 28, 2014 Share Posted October 28, 2014 I've got Yosemite running nearly perfect on my Precision M6500, except I cannot use any USB devices. During startup I get the following errors: 10/28/14 12:41:26.000 AM kernel[0]: USBF: 1.333 AppleUSBEHCI:: unable to get filterInterruptEventSource 10/28/14 12:41:26.000 AM kernel[0]: USBF: 1.333 AppleUSBEHCI::UIMInitialize - Error occurred (0xe00002be) I have tried patching my DSDT like a thread on a Google search mentioned, but it did not help. I have even tried disabling things in the BIOS to free up IRQ, as well as tried disabling "USB Emulation". Still nothing. It may be important to mention I am MBR booting into Clover. Everything else is working fine from what I can tell. FireWire is detected, Audio and LAN work after some external kexts, Nvidia works with QE/CI (when I use "Inject Nvidia" with Clover, otherwise I just reboot). But I just cannot shake this USB problem. Any ideas? EDIT: Nevermind, the patch did work, I just did it wrong. Here is a working DSDT DSDT.zip Link to comment Share on other sites More sharing options...
