[GUIDE] USB Fix El Capitan 10.11

How to fix Intel USB ports in OS X El Capitan

my thanks to stinga111 and VCH888 for contribution in USB problems

After some time try to fix USB ports on El Capitan, I just realize that 10.11 has a new mechanism to constraint the USB ports to your SMBIOS. If your Intel USB ports work just fine (without GenericUSBXHCI) but stop working on 10.11, it's probably your ports are not defined in SMBIOS.

The ports may work after you change to another SMBIOS with suitable ports, but you can edit the ports for your SMBIOS.

1. Load the USB kexts

The new kexts controlling USB in 10.11 are AppleUSBEHCIPCI.kext and AppleUSBXHCIPCI.kext inside IOUSBHostFamily.kext. You can check the ports of your current SMBIOS by opening these files:

USB 2.0

/System/Library/Extensions/IOUSBHostFamily.kext/Contents/PlugIns/AppleUSBEHCIPCI.kext/Contents/Info.plist

USB 2.0 and USB 3.0

/System/Library/Extensions/IOUSBHostFamily.kext/Contents/PlugIns/AppleUSBXHCIPCI.kext/Contents/Info.plist

System will now attach AppleUSBEHCIPCI kext to device name EHC1 and EHC2 by default, you can check the info.plist:

So make sure your USB 2.0 device name is already in the kext. You can change IONameMatch to match the USB 2.0 name in DSDT, or you can rename USB 2.0 device in DSDT to EHC1/EHC2 (depend on SMBIOS in info.plist)

For USB 3.0, it's different. Instead of using name (IOMatch), AppleUSBXHCIPCI will use ID to attach kext to USB 3 device in DSDT

So even if your USB 3.0 device is renamed XHC1 or XHC, the kext will load if your device id is matched.

2. Ports Restriction

Even when the USB kexts are load, it still does not mean that all the ports in your system work, because Apple has implemented a new method to control which ports are available for a SMBIOS.

Please note that if your USB 3.0 device is not named XHC1 (typically XHC), there is no port restriction by default, but if all your ports do not work completely, you may want to enable port restriction and add your ports manually.

For example, in iMac 13,1 SMBIOS:

By default, for EHC1, there is one port available (port-count 01000000=0x00000001 bit flip) and that port is at address 1, note that the port name is not important. If your system has more ports at other addresses, those ports will be disabled!

The same for XHC1, MacBookPro 9,2 will only have ports at address 1, 2, 5, 6 available:

To fix the problems, there are two methods: remove ports restriction or adding ports.

2a. Remove Ports Restriction

This is the easy way, you just need to remove port-count and ports in info.plist, system will auto grab the ports from your DSDT!

For USB 3.0, you can also remove port-count and ports, or just name your USB 3.0 device in DSDT to XHC (actually any name, out of XHC1).

Some SMBIOS like iMac14,x do not have port restriction for USB 2.0, so you can set those SMBIOS if you get "still waiting for root device" caused by not-working USB 2.0 ports

However, Apple set a limit of 15 ports for one USB device, so if your DSDT define more than 15 ports, only first 15 ports will be recognized by system! In this case, you have to enable ports restriction and add your ports as guided in 2b.

2b. Add ports to Ports Restriction

In this method, you will enable port restriction and add your ports.

To enable port restrictions:

- For USB 2.0, rename your USB to EHC1/EHC2 or change IONameMatch.

- For USB 3.0, rename your USB to XHC1 or change IONameMatch.

Then, you have to identify which ports you have in your DSDT. For example, my XHC1 has ports at 1, 2, 3, 4:

However, the SMBIOS MacBookPro9,2 I'm using only contains ports 1, 2, 5, 6 (note that port name is not important):

So I had to add ports 3 4, and the ports work again!

Please note that there is still a limitation of 15 ports (discovered by VCH888). For example: If your DSDT defined 14 USB 2.0 ports HS01->HS14 and 6 USB 3.0 ports SS01->SS06, OS X will only recognize HS01->HS14 and SS01.

To fix this problem, you have to identify which ports are real and which ports are unavailable, then add only valid ports. You can find example here: http://www.insanelymac.com/forum/topic/306777-guide-usb-fix-el-capitan-1011/?do=findComment&comment=2147401

3. Injector USB kexts

Instead of editing kexts directly, which will be lost after OS X update, you can use injector kexts (thanks to RehabMan).

If you want to edit info for your USB 2.0 (controlled by EHCI), make sure you rename EHC1/EHC2 in your DSDT to something else (like EH01/EH02), so that the EHC1/EHC2 port restriction in original Apple kexts does not apply to your system, then you create an injector kext (which is basically a Info.plist) to add port information to your new EH01/EH02.

For USB 2.0/3.0 controlled by XHCI, make sure your XHCI device is not XHC1, so that the XHC1 port restriction in original Apple kexts does not apply to your system, then you create an injector kext (which is basically a Info.plist) to add port information to your new XHCI.

You can take example of the kext here: https://raw.githubusercontent.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch/master/USBXHCI_4x40s.kext/Contents/Info.plist

Just create a folder YourKext.kext/Contents, copy Info.plist to Contents folder and edit info.plist to suit your need.

Perfect!

Thanks pokenguyen

I noticed something strange going on during recent experiments with the Haswell BRIX and 10.11.

If I applied by normal XHC->XHC1 rename patch, I had non-working USB3 (all ports on the BRIX are USB3).

I hadn't looked into it in detail, as omitting the rename from my DSDT patch script fixes, but then I run across this post and it explains why.

For me all port work by Default!!

RehabMan · June 22, 2015

For me all port work by Default!!

Your USB3 device in DSDT is probably not named XHC1. XHC is typical.

crusher · June 22, 2015

Your USB3 device in DSDT is probably not named XHC1. XHC is typical.

Yes. His name is XHC

RehabMan · June 22, 2015

Yes. His name is XHC

Why it works is explained in post #1.

crusher · June 22, 2015

Why it works is explained in post #1.

I know!!!

RehabMan · June 22, 2015

I know!!!

OK. It wasn't clear you realized that from your post #4.

GA-H61-USB3

USB3 works on 10.10 not on 10.11

Using DSDT but my DSDT has no mention of XHC anywhere.

How would I go about adding those ports into my DSDT?

GA-H61-USB3

USB3 works on 10.10 not on 10.11

Using DSDT but my DSDT has no mention of XHC anywhere.

How would I go about adding those ports into my DSDT?

Yours is not Intel USB 3.0, please read carefully.

This topic is mainly for Intel USB.

What kexts did you use to enable usb3 on 10.10?

BNZfive · June 23, 2015

No kexts used, USB3 works natively. I believe my board has the FL1009 controller which is supported natively by the 10.8-10.10.3 kexts

My main question is:

How can I add xhci devices to my DSDT? As that has more to do with the configuration of my MB than chipsets and whatnot.

I have looked in repos for Maciasl and have found nothing to help on this issue.

I understand you say this is for "Intel only" but if I could have xhci added to my DSDT we may find out if it is possible to work on other supported (by apple) chipsets.

VCH888 · June 23, 2015

Great topic.

USB3_H87M-HD3.zip

Need to update version of dependencies in OSBundleLibraries of each update yourself.

I did this dummy kext for getting USB3 to work on my H87M-HD3 on the same date of this topic. What a coincidence!

Front USB3 will be not working because there is limitation of items (15 items) that will be handled by AppleUSBXHCIPCI.kext. Four USB3 ports on the back panel are working for USB3 devices as well as they are working for USB2 devices. Four USB2 ports on the internal USB headers and two USB ports on the back panel are also working. So, maximum devices can be up to ten devices, see Max_USB_ports,jpg, (12 devices for Windows).

Ports may be up to identify which ports are working due to different hardware.

H87M-HD3 & smbios as MacBookAir6,2

- tested with XHC in dsdt and without editing kext, see XHC_00.jpg. It showed 15 items. USB3 ports on the back panel were not working for USB3 devices.

- tested with XHC1 and without editing kext, see XHC1_no_Dummy.jpg. It showed items (some ports were working) that related to original kext.

- tested with XHC1 and editing kext, see XHC1_02_Dummy.jpg and XHC1_02_1_Dummy.jpg.

- The key of each port is a port address, not a name. Two port addresses may share the same physical port, see XHCI_USB3_USB3COMBO.rtf and dsdt.dsl.

update 06/25/2015

What UsbConnertor in info.plist is? (based on my testing devices)

0xFF in USB3.0 (address) showed an USB3.0 external HDD as an internal HDD on Desktop.

0xFF in USB2.0 (address) did not show USB2.0 stick on Desktop (can see through Disk Utility) but it showed an USB3.0 external HDD as an internal HDD.

0x00 in USB2.0 (address) showed an USB HDD/Stick as an external device.

HS_SSP.jpg

HS_SSP1.jpg

From HS_SSP.jpg, there are 14 connections.

Two connections will use the same connector, for example;

see SSP5 and SSP6 in HS_SSP.jpg, connecting to USB3 external HDDs, USB3.0 natively.

and

see HS09 and HS10 in HS_SSP1.jpg, connecting to USB3 external HDDs because of missing SSP5 and SSP6 in dsdt.

Note: please see my dsdt about HS##, SSP# and Name (_ADR, 0x##).

Source: http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/8-series-chipset-pch-datasheet.pdf

Example ports of H87M-HD3 are related to Device (name) in my dsdt.

HS##  High Speed (USB 2.0)
SSP#  Super Speed (USB 3.0)
Both HS## and SSP# will be controlled by XHCI Controller of Intel 8/9 series chipset. 
EHC# will be controlled by EHCI Controller of Intel 8/9 series chipset and normally will not be used by the OS.

* The important thing is to have the right address of each port, such as <01000000> or 0x01.

USB3.0 (Front), depends on USB 3.0 front ports.

MacPro6,1 has Fresco Logic FL1100 for USB 3.0 so I think you can use PCIe USB 3.0 card with FL1100 for your old MacPro and PC.

What is your FL1009 device id?

I don't see FL1009 in XHCIPCI kext, but I found one for FL1010

		<key>AppleUSBXHCIFL1100</key>
		<dict>
			<key>CFBundleIdentifier</key>
			<string>com.apple.driver.usb.AppleUSBXHCIPCI</string>
			<key>IOClass</key>
			<string>AppleUSBXHCIFL1100</string>
			<key>IOPCIPrimaryMatch</key>
			<string>0x11001b73</string>
			<key>IOPCITunnelCompatible</key>
			<true/>
			<key>IOProbeScore</key>
			<integer>1000</integer>
			<key>IOProviderClass</key>
			<string>IOPCIDevice</string>
		</dict>

So you may have luck changing IOPCIPrimaryMatch to match your FL1009 id.

A quick google search shows that fl1009 id is VEN_1B73&DEV_1009, so you have to change 0x11001b73 to 0x10091b73. Hope it works for you.

I gues

Thank you! I don't realize that there is a limitation of 15 ports in the kexts. Will update the topic now.

Are there a quick way to identify which ports in dsdt are real or not? Or you have to add each port to kext upto 15 and try?

Guys thanks for the Guide pokenguyen i have one issue i use those Injector kext my USB 2.0 is working fine but my USB 3.0 not detected help is needed

What is your USB 3.0 id? Intel or other brand? How did you enable it in 10.10?

Dec_Bra1n · June 23, 2015

What is your USB 3.0 id? Intel or other brand? How did you enable it in 10.10?

i use GenericUSBXHCI kext in 10.10.4 i guess i use renaissance usb 3.0 driver on windows

and see this image on 10.11

pokenguyen · June 23, 2015

For USB 3.0 devices not supported natively by OS X, you have to wait until GenericUSBXHCI.kext is updated for 10.11.

Dec_Bra1n · June 23, 2015

Ohk thanks ......i will surely wait for it

Thanks for help :angel: :angel: :angel: :angel: :angel:

mendietinha · June 23, 2015

the fix didnt work here. usb 2.0 only.

EDIT: working after inject via fakesmc. thanks to artur for the tip.

pokenguyen · June 24, 2015

EDIT: working after inject via fakesmc. thanks to artur for the tip.

You mea copying content of injector kext to FakeSMC? It's probably a problem of probe scope, the order of kexts loading...

mendietinha · June 24, 2015

You mea copying content of injector kext to FakeSMC? It's probably a problem of probe scope, the order of kexts loading...

i copied from the apple kext itself. the only smbios who solved the problem was mbp11,1. so i first copy paste over mbp6,2 and 6,1. it worked too. ill keep an eye on it and if the problem dont get fixed for final release, will use the injection like it is or a kext.

the problem never was not recognize the ports, it was reading what i plug in it.
