USB Keyboard not working after sleep

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.

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.

I have a MacBook Pro (13-inch, 2018) with a Mac USB keyboard via a usb c hub. I just ran the OS updates and have 10.14.6. Now the keyboard is not working. Was before, and before you ask it's not the USBC hub. I just tested it and its working fine with my PC. Trying to run a business here APPLE!

Same as everyone else.

Macbook Air 2020

USB keyboard is connected through an Anker USB-C Hub with PD and HDMI.

Keyboard functionality is regained by unplugging and replugging it after waking the system.

I'm having the same issue with my Macbook Pro 13" 2017 (MacBookPro14,2). Catalina10.15.6

My keyboard is connected to the usb hub built into my monitor. Laptop remains closed next to it. My Logitech G Wireless mouse works fine and wakes up the device from sleep but the keyboard remains unresponsive until I unplug and reconnect it.

I can't believe this is still an issue since Oct last year. But it is relieving to hear that I'm not the only one. If there's so many of us there must be many more who haven't found this thread.

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".

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 ?

What exact Mac is this ? /model /year /size /retina /touchbar is this

and

what exact macOS you are currently running?

It's very annoying!
