External USB Keyboard/mouse randomly stops working on New MacBook Air Early 2020 model running Catalina 10.15.4

Subject says it all for the most part. I have an external USB hub connected to one on my Thunderbolt 3/USB-C ports on my MacBook Air early 2020 model running Catalina 10.15.4. At random times during the day (2-3 times a day) my Logitech G602 mouse and external Apple Keyboard will stop responding completely and only a reboot will restore functionality. The USB 2.0 HUB under System Information->Hardware->USB completely disappears until the MacBook is reported. Disconnecting/reconnecting the USB Hub does not resolve the issue. I have attached a screen capture of what the USB device looks like normally when things are working correctly. This MacBook Air has replaced a late 2019 MacBook Pro that was running Mojave and then Catalina 10.15.4 for the last 2 days of use. Using the same USB hub and external devices I did not experience this issue with that configuration. Granted I only was running Catalina for 2 days with the MacBook Pro 2019.


Things that I have tried to resolve the issue. Looking for additional suggestions to fix or troubleshoot the issue. I feel that my new MacBook Air is a big paperweight at this point.


  1. Reset NVRAM
  2. Reset SMC
  3. Startup in Safe Mode
  4. Ran Diagnostic check that came back clean.

Yeah, on my MacBook Air 2020 my wireless usb mouse cuts out too when using the 2.4ghz USB A receiver plugged into the USB A ports on my USB-C hub. My workaround is using a USB-A to USB-C adapter, and plugging that into the USB C port on my hub, and for some reason that solves it. But when the receiver is directly plugged into the USB A ports on the hub, it intermittently cuts out.


It's annoying, and the solution I have to live with for the time being is ridiculous. Apple please fix this!
