10.10.4 Keyboard not working after sleep (mac min)i

I'm speaking about the keyboard physically built into my MBP.

I do not have an external keyboard to test. But, my other USB devices (iPhone, external hard drive) do not operate when the issue occurs. So, for me, all USB connectivity ceases. The only way to resolve is to power cycle.

In my case the problem appears with an external USB hub where the devices are connected, which then do not operate any more. Those both USB hubs, which had trouble (2.0 and 3.0) have an own power supply. Hence the possible regular reason for a not operating USB port: over consuming of the supply current - surely was never the case at my environment.

But your remarks could indicate that your multiple devices are possibly the reason for the „regular“ case above. Please check, whether your USB problem appears, even if you attach only externally supplied devices. Many external hard drives and surely the iPhone take the USB power instead.

But even in this case the missing rewake from over load would be a bug and probably the same.

It would be interesting, whether you could reduce the bug appearance by reducing the current consumption.

I discovered a simple solution. Turn ON Power Nap. That might not satisfy conservation purists or those who just want it to work like it's supposed to, but it solved the problem for me. I didn't read through the 60 replies to see if this has already come up, but since more often than not I come away from these forums no wiser than when I started looking, I thought I would share something that did work for me. Until Apple properly addresses the issue, this is a decent compromise.

Hello community,

after my bug report Apple closed it with this result:

Engineering has determined that this is an issue for a third party to resolve.

The usb interfaces are still opened() by something which will prevent them from terminating.

There is a RIM kext installed on the machine which may be causing this.

This a 3rd party driver.

After checking my /System/Library/Extensions folder I found those two RIM extensions:

• RIMBBUSB.kext
• RIMBBVSP.kext

Searching for the origin in the Internet I did not revealed it. Instead those are part of multiple other error reports.

In any way those are elder (2013) stuff. Hence I simply put them to the trash.

Because the USB bug does not appear always, I shall do some days testing before I shall confirm this as a solution.

Probably I shall find out, what application does not operate anymore, because of the missing drivers.

Greetings,

Harald

Observation over multiple days has shown that the problem has gone.

Happening to me now on 10.12.1 (16B2657). Any fixes for this?

Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time.
