Usb port stops working after a while on new 2020 mac book pro13, mac OS catalina 10.15.4

I've tried a couple of dongles, including apples own usb-hdmi-usb-c dongle, to connect my hdmi and mouse via usb, however after about 2 hours of use, the usb port just stops responding and my mouse is no longer able to talk to the laptop.

The hdmi port seems fine and there is no issue with the secondary screen connection, but I need to un-plug and plug the dongle back into the laptop's usb-c port in order to get the usb port to respond and use my mouse again.


Until I reconnect the dongle, it doesn't matter what device I plug into the usb port.


What do to?

MacBook Pro 13″, macOS 10.15

@klass226 It is similar with me. Although I'm plugged directly macbook power adaptor, my dongle only starts to work again if I unplug it completely or if I put the laptop to sleep and then wake it up it. Simply unplugging the usb adaptor for the mouse from the dongle does absolutely nothing.


It is mighty strange. You'd think Apple would not this issue so far into the game.
