Asmedia 1042: GenericUSBXHCI loaded but USB ports do not work

[toto1234]

USB3 with Asmedia used to work on 10.11. I'm installing 10.12 on this motherboard (XH61V) with Enoch r2883 and everything but USB3 works

 

GenericUSBXHCI appears to have been loaded correctly:

But the ports do not work (and nothing shows up in System Information). If anyone has an idea to fix this, I'd be very grateful.

Are you sure they are not working? They just won't show up, but do work fine.

Test your speeds with and without the kext loaded...

They are not working at all, nothing will work when connected to them.

Try these

If you put your signature hardware better

Many thanks carlo_67.

 

In the meantime I found the problem and the solution:

 

Both VoodooHDA.kext and GenericUSBXHCI.kext have to be placed in SLE instead of /Extra/Extensions.

 

This is weird because I boot with -f anyway, and other kexts (FakeSMC*, NullCPUPowerManagement and RealtekRTL8111) work fine in /Extra/Extensions

EDIT: a better fix is to plug in a USB3 hub at boot, then devices can be disconnected and reconnected after and still be detected.

 

Actually I think I found the real fix: to have the device I want to use plugged into the USB3 port while OSX boots.

Put your signature hardware

At least it can help
