I've found the issue!

The boot flag "-gux-defer-usb2" was the problem. Unchecking it in Clover Configurator makes the webcam work again.



Have a nice sunday! :)

Now I discovered another issue. Removing "-gux_defer_usb2" makes the webcam work, but the laptop doesn't go to sleep and remains in black screen...

Ok thank you for the information! Sorry to bother you again. Now I noticed one error, which is not very important for me, but it would be gorgeous to resolve it. The HP truevision webcam is not working. Do you know where I could look to find the origin of this issue? I have no clue...

Could be a USB issue.

You could try using AppleUSBXHCI instead of GenericUSBXHCI...

That's what I'm using on the Lenovo u430. Requires DSDT patches and doesn't work for all...

I've tried different AppleUSBXHCI.kext Versions (650.4.3, 670.4.0). With that kext, the webcam and the usb3 is found like with the GenericUSBXHCI.kext, but sleep doesn't want to work with it, ending in a black screen which it isn't wakable. I searched in the web for clover kext patches or DSDT patches regarding the AppleUSBXHCI.kext, but I didn't found anything.

A question: Does it make a difference if I put the kext in EFI/CLOVER/kexts/10.9, in S/L/E or in S/L/E/IoUSBFamily.kext/Contents/PlugIns?
