USB Keyboard not working after sleep

Brand new 2020 MBP 16" not working.

2 official Apple keyboards sadly not working. Detached everything and reboot, reinserted etc. All the USB ports work with other devices fine. The ONLY thing that worked for me was an SMC reset. What a royal PITA! Everything worked fine under Sierra, High Sierra etc. I have 6 Macs in my house so it is definitely something that got changed with Mojave and is continued over to Catalina.

Please help Apple!

I've been following this thread since the Catalina update, with the same issue with my Apple USB keyboard very rarely connecting with my MacBook Pro (Retina, 13-inch, Early 2015). I tried all of the suggested fixes with no success: resetting SMC, starting up in safe mode, etc. and an evening spent chatting to Apple support who suggested reinstalling the entire OS (I'm not THAT bothered) out of lack of other options. I eventually tried a last gasp that I saw on another forum for a similar issue. I connected a USB extension cable to my keyboard, and plugged that into the MacBook and for whatever reason, that has solved the issue! Thoroughly annoying, and I hope they fix this is the next OS update.

Had this problem for months as well. Tried all the usual resets (SMC, PRAM, etc.) without success. This would also happen on both my Macbook Pro's (2016 and 2017). I did a combo update with 10.15.4 last week and I have not had that problem since.

Update 10.15.4 seems to fix this issue.

I also have the same issue with a MacBook Pro 15-inch 2016. My keyboard that is routed through a couple of USB hubs (one in a LG monitor and a second USB 3.0 4-port Hub with power. About 50% of the time after sleep the keyboard doesn't work. I have to pull the LG USB3 monitor link and reinsert to revive the keyboard, sometimes this takes a few attempts.

I was only focused on the keyboard but also found that my USB attached Bose sound system connect to that USB hub also was not working on wakeup. Again when I disconnect the LG monitor to which the Hub is attached for the keyboard and Bose and reconnect things work again.

Now just today, I have Thunderbolt attached Drobo through a USB3 to Thunderbolt adapter. If the MacBook sleeps the Drobo does as well but the Drobo doesn't wake up when the MacBook does and remains in sleep mode.

Now here comes my hardware background. On the PCI bus (where the USB Controller would be attached) as per the specification a reset signal should be asserted (I believe for 100 ms minimum) on wakeup or reboot. In hardware designs using system on modules in the past we had problems where firmware and os drivers were not asserting that signal long enough causing a very similar problem. Now I am not sure if the USB within the MacBook may not be started properly until it gets the insertion interrupt or if the USB downstream is messed up. But this would be the first place I look (Apple).

Here is the hardware capture of my USB: -- Hope it helps

Since October of last year I was dealing with this problem in 2 different notebooks (MBP 13" 2019 and Macbook 12" 2016, both with Catalina 10.15.4 and external Apple USB Keyboard). About one month ago, tired of waiting for a solution and based on some posts I read, I did a full clean install. Problem solved. Not the best solution, but I never had any other problem with my keyboards or other USB devices since.

When you have the problem, open Terminal and run-

sudo kextload /System/Library/Extensions/a*

Unplug and plug back in your USB devices.

I've been trying to narrow down which kext is getting unloaded, and this is as far as I've gotten. This doesn't fix the issue, but gets things working to avoid a restart.

I reported the same problem on this post a number of weeks ago.

I can now report that since the latest update last week (10.15.3) the problem seems to have resolved. I used to get this issue 3 or 4 times a day and since the update last week I have not had a single instance of the keyboard failing to wake up with the system through multiple USB hubs.

I hope this applies to everyone but it is currently what I am experiencing.

I have been following this thread for months (I posted about it in the end of 2019), with the same issue, upgrade after upgrade. Interesting the conversation from ajrigby24 with Apple support: last week, I did a CLEAN install of my Mac (Catalina 10.15.3). Since then,I have never faced this problem anymore - it seems that the issue was solved.

Update to Latest version (10.15.3) issue is still there. Need to unplug and plug in USB hub before it works again.

Same issue:

MacBook Pro (16-inch, 2019)

macOS 10.15.5

If I unplug my keyboard and plug it back in, it usually fixes it.

Each day starts with me waking up a sleeping computer and not having a USB wired keyboard connection!

Fortunately, the reset of holding down power button after shut down for 10 seconds works every morning for me.

Still, as a "PRO" it would be nice for me to arrive in the studio and start working immediately before ideas are lost....

:(

On recent MacBook Pro, when the computer sleeps, it may drop power to external USB devices. Depending on how well your USB Hub does at re-connecting you results may vary from "never misses a beat" to "stops working completely until the next restart".

This trick may work: plug a usb memory in the affected Mac usb port, wait for MacOS to read it, and then re-insert the Apple Keyboard usb cable.

I have this problem too. After I wake up the laptop the USB keyboard does not work unless I disconnect and reconnect it (sometimes more than once).
