Native Intel Panther Point USB 3.0 Patch for 4540S

Status
Not open for further replies.
As far as I know MacBookPro8,1 doesn't have USB 3 ports. Honestly I don't care about USB3, but my USB2 ports don't work without removing that "AppleUSBXHCI.kext" plugin. It would be nice if we could make at least the USB2 ports work without touching IOUSBFamily.kext.
 
I found the original MacBookPro8,1 ioreg.
MacBook Pro8,1 "Core i5" 2.3 13" Early 2011 A1278 | MC700 2.3GHz/4GB/320GB/HD Graphics 3000/SD

This how EHC1 looks in the original ioreg (notice the device id: 1c26):
EHC1.png

and EHC2 (notice the device id: 1c2d):

EHC2.png

In Rehabman's patches I see different value for EHC2. His patches set 1c26 to both EHC1 and EHC2:

Isn't better to set EHC2 to 1c2d like the real MacBookPro8,1?

Yes I think it's a good idea. Waiting for confirmation...
 
I'm wondering what SystemDefinition Rehabman uses.

I don't think it's a good idea using previous generation chipset Id's since 4540S HM76 is supported natively by OS X.
If you used IvyBridge Beta Installer, did you restore back AppleUSBXHCI.kext ? Also any PXHCD.kext would interfere with native support.
Having that what do you mean by "Nothing happens for me"? Can you more specific like:
Do USB2 devices work on USB2/USB3 ports?
Do USB3 devices work in USB2 or USB3 mode on USB3 port?

output of this command will be helpful

system_profiler SPUSBDataType

Yes, I'm using vanilla IOUSBFamily.kext. No PXHCD installed.

BigDonkey said:

Not really. Only one port is working. By "working" I mean that I can attach an iPod or external HDD to the USB port, and the operating system recognizes it. The three USB ports that are not working are unable to recogonize external devices other than a mouse or keyboard (no storage devices).

BigDonkey said:

Click to expand...
I don't have any USB3 device and don't think I will purchase one soon. I would be happy to have full USB2 support. I can do that by removing AppleUSBXHCI.kext, but I though your patch can help me use all ports as USB2 without removing that plugin.

I send it a bit later. I'm not home right now.
 
A4Tech is a mouse connected to the USB port and JetFlesh is a flash drive.
This is how my USB ports look after applying your patch.

It looks pretty normal and your IOReg is very similar to mine. I booted with 8.1 definition, works in my case. Someone with access to both processor types could swap them and shed more light.
