USB Keyboard not working after sleep

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).

MacBook Pro (Retina, 13-inch, Early 2015)

macOS Catalina 10.15.3

Regardless of what they report, Apple USB keyboards are very close to the MAXIMUM USB power draw, and their cable is small to allow it to be flexible. If you use an "extensions cord" or have ANY device other than a low-power USB mouse plugged into the keyboard or on the same USB bus, it will slightly over-draw USB power and go flaky.

You can check which USB bus is which in this pane:

 menu > about this Mac > (system report) > Hardware > USB ...

then scroll through the list to see what devices are on the same USB BUS, sharing power.

Same here. It started happening after I updated to Catalina on my MBPro 15". Then I got a new 16", installed everything fresh (no data/profile migration) and the issue still persist.

It's likely a Catalina issue, not a problem with your keyboard.

I have the same issue here after upgrading to Catalina.

USB Keyboard and mouse is plugged into the monitor's USB hub, and a USB-C cable to the Mac. After a wake up from sleep keyboard and mouse don't respond. I have to unplug and plug the USB-C cable back a few time before it starts to work.

2016 13inch Touch Bar MBP on Catalina 10.15.1

It is really frustrating.....

Same problem here since Catalina upgrade with USB Apple Keyboard and HooToo USB C adapter (HDMI).

Need to unplug, plug again multiple time to make everything works (mouse + keyboard + display).

Really annoying....

I have same issue with MacBook Pro Early 2015 after Catalina upgrade. I have an external monitor with a USB hub connected, a mouse and keyboard connected to the USB hub. When I connect the hub to my laptop, sometimes the mouse and keyboard do not work, sometimes the problem occurs after waking up. Re-connecting the USB cable several times helps.

Not for me. :( I have the latest Catalina update (10.15.3), but I still have problems with my external USB keyboard and nothing has changed since I posted about it some months ago. Usually I need to unplug ang plug again my keyboard about 3 to 4 times (sometimes just rebooting works) until it is recognized by my Mac.

MacBook 13" 2020 and wired Apple USB extended keyboard. Same problem happened only after 10.15.6 update. Never had this issue before. Is there anyway to change the sleep level or something so that USB bus will stay on during sleep ?

Same problem here. I have a Macbook Early 2015 with an Apple USB external keyboard. If I put my Macbook into Sleep, my Logitech mouse can wake the Mac, but the keyboard does not work anymore. I have posted a similar question before in this forum and it was suggested to reset the SMC and restart the Mac in safe mode. Safe mode solved the problem for a while but, after some "sleeps", the problem happened again.

Same to me. MacBook Pro 2016 13", Apple keyboard connected by USB to USB-C adapter. Prior Catalina sleep mode was no issue. Now I always have to reboot to get Catalina recognizing the keyboard again. This is so annoying!!! Deletion of "magic files" or SMS reset did not help. Apple, please fix this!!! 

I have the same problem using a 2018 MacBook Pro 15 (w/ Catalina). My laptop is docked, and this happens both when the keyboard is connected through a USB hub, or connected directly to the Mac through Apple official HDMI adapter. It's really annoying to have to unplug the MacBook, remove it from the dock and open the lid so it wakes up, and then connect everything again and close it. That's the only way to force it to wake up. It doesn't make any sense that a professional grade machine has such an obvious flaw.

Have the exact same issue. I have external Dell monitor connected to my MacBook Pro (Early 2015) and external bluetooth mouse and external Apple keyboard and magic trackpad 2 connected. Every time the USB keyboard stops working as soon as I plug it out and plug back in and the same is true after my laptop goes to sleep. I have to repeat plugging in and plugging out the keyboard USB to my laptop and after several tries it start to work again. Very annoying.. 😔

My Bluetooth keyboard stops working periodically. I have a new Mac Mini (2018). Have found that going to login screen and logging in again resolves this problem. I believe it to be a fault with Catalina as I've not had this issue with my older MacBook Pro running High Sierra.

I'm having this problem too. New 2020 MacBook Pro running 10.15.4 with a wireless keyboard/mouse plugged into an LG monitor plugged into the laptop. I've had my mouse and keyboard just stop working twice in the week since I got my new laptop.

I have used this setup for nearly 3 years with my previous MacBook Pro which I never upgraded past Mojave and never had an issue.

Plugging the usb transmitter directly into the laptop does not fix the problem. Turning the mouse off/on doesn't fix it. The batteries are fine (replaced them anyways and that didn't fix it).

Restarting the computer and unplugging the monitor and plugging it back in has solved it the two times but that kind of BS sounds like something I'd expect for Windows, not Mac.

Same here. I'm using a brand new 16" MacBook Pro, Apple wireless "magic keyboard", and external monitor, with laptop lid closed. I thought it was because of the new hardware keyboard, but found this thread searching for an answer.
