Any other MBP users experiencing keyboard & trackpad pauses/stalls with El Capitan?

Are other MBP users experiencing pauses & lost input with the built-in keyboard & trackpad since upgrading to El Capitan? At least once every 90 seconds the pointer freezes and the keyboard stops accepting input. Activity Log reports errors that the device is not ready (see below) . This is happening on a virgin installation onto a reformatted hard drive with no third party software installed. I restored the system to Yosemite and the problem went away. Then performed a second, fresh install and the problem returns. It occurs even during the OS installer itself indicating this is a kernel extension or Apple driver bug. When booting Yosemite from and external drive their is no problem so I'm confident it's not defective hardware

This issue is specific to all version of El Capitan.

1/19/16 6:32:04.000 PM kernel[0]: USBF: 1409.535 IOUSBHIDDriver(AppleUSBMultitouchDriverNoShim)::RearmInterruptRead returning error 0xe00002d8 (device is not ready), not issuing any reads to device

1/19/16 6:34:46.000 PM kernel[0]: USBF: 1571.674 IOUSBHIDDriver(AppleUSBTCKeyboard)::RearmInterruptRead returning error 0xe00002d8 (device is not ready), not issuing any reads to device

Workaround is to use a Magic Trackpad and USB Keyboard.

MacBook Pro, OS X El Capitan (10.11.2)

Try a restart.


Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.


Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.


Isolating an issue by using another user account


If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Hello everyone

It's exactly the same for me with my MBP early 2008 4.1. core2duo 4gb 512 gb SSD 850 EVO Samsung

The system.log fills touchpad driver problems and "device is not ready".

I am very very disappointed by Apple's practices. They publish all lists of compatible machines "el capitan", but this is totally false! Apple has only one objective to develop its sales and does not care about our machines a little old yet in perfect condition.

The touchpad and keyboard lock every 60-90 seconds! Obviously the driver is absolutely not compatible.

I just put my old Mavericks that works very well. Wait a while (a few months! Or years!) To install "El Capitan!

"Recommended suggestion" is a FAIL.

Restarting: Does not resolve this issue, as was described in the original post.

Backing up and restoring: Does not resolve this issue, as was described in the original post.

Creating another admin account: Does not resolve this issue, as was described in the original post.

Disconnecting all peripherals: Does not resolve this issue. No peripherals were connected initially however connecting an external keyboard and trackpad provides a workaround to this bug.

Disabling/Deleting all third-party software: Does not resolve this issue, as was described in the original post. This is unrelated to this issue as no third-party software whatsoever was installed on the MacBook Pro.


Downgrading to the previous major version of Mac OS X solves the problem as noted in the original post.


It's looking like the only solution is to not run El Capitan on a MacBook Pro 4,1 most likely because Apple's own HID drivers are incompatible with this model of Apple product.

Update: The problem is still present in the release version of OS X 10.11.4 but doesn't happen on all early 2008 Macbook Pro (4,1) systems with nearly identical specs.


When reporting this issue, please included your processor speed and video RAM with your specs, and if you have a rotational hard drive. This may be relevant.


I installed the release version of 10.11.4 onto an external USB drive attached to my 'Macbook Pro 15" (early 2008)' with 2.4 GHz Intel Core 2 Duo and 256 MB of video RAM, original rotational HD. The USBHID problems with keyboard and internal trackpad still occur even during the OS installation, and subsequent reboot. Booting from either external or an internal drive running 10.11.4 made no difference.


When I boot from that USB drive containing 10.11.4 to my nearly identical "Macbook Pro 15 (early 2008)" with 2.6 GHz Intel Core 2 Duo and 512 MB of video RAM, with upgrade to SSD, the problem does not occur on that system! This indicates only some systems are susceptible to this Apple USBHID bug.

On both systems the keyboard, trackpad and IR receiver share the same USB bus. I compared the USB details for the bus that the keyboard & trackpad are on and they are identical across both systems:

USB Bus:

Host Controller Driver: AppleUSBUHCIPCI

PCI Device ID: 0x2832

PCI Revision ID: 0x0004

PCI Vendor ID: 0x8086


Apple Internal Keyboard / Trackpad:

Product ID: 0x0230

Vendor ID: 0x05ac (Apple Inc.)

Version: 0.70

Speed: Up to 12 Mb/sec

Manufacturer: Apple, Inc.

Location ID: 0x5d200000 / 3

Current Available (mA): 1000

Current Required (mA): 40

Extra Operating Current (mA): 0

Built-In: Yes


IR Receiver:

Product ID: 0x8242

Vendor ID: 0x05ac (Apple Inc.)

Version: 0.16

Speed: Up to 1.5 Mb/sec

Manufacturer: Apple Computer, Inc.

Location ID: 0x5d100000 / 1

Current Available (mA): 1000
