After applied the June 2021 Firmware Update for Surface Laptop 3, this issue occurs:
- At the first time plugging a External SSD into USB-C port, it works fine. But when you click Safely Remove Hardware in notification area (but keep the device plugged), the Device Manager shows that the Storage Controller of the device got something wrong.
- After pulling off the external SSD, any other device doesn't work USB C port; sometimes the USB A port fails too. Device Manager reports a Unknown USB Device (Port Reset Failed), with an error code 43. Windows Hello Camera might fail because of this.
- Now, the computer cannot manage to shut down or reboot. After the "Shutting Down/Restarting" mono-colour screen disappears and the monitor turns off, the fans keep rotating and the back-light of keyboard is still on. One can only force the laptop to shut down by long pressing the power button.
- After re-start the computer, problems can reoccur following 1. to 3.
By the way, this error seems making the computer fail to enter hibernation from sleep, which induces heating of the computer in backpack and extreme battery drain.
On Reddit there are lots of report on similar issues:
Surface Laptop 3 not shutting down properly and battery draining a lot during sleep
Surface Laptop 3 battery drain after shut down
SL3 is overheating in my backpack, even when the device is turned off. What is going on?
Also, on Microsoft Forum:
Surface laptop 3 hot and won't turn on
Battery drain during sleep
Surface Laptop 3 does not completely shutdown.
I've tried reset my computer, which does no help. I do hope Microsoft can handle this issue as soon as possible.

After installing the 23 July 2021 updates](https://support.microsoft.com/en-us/surface/surface-laptop-3-update-history-7471eff4-8de2-1616-5b7b-241e28c2236b "https://support.microsoft.com/en-us/surface/surface-laptop-3-update-history-7471eff4-8de2-1616-5b7b-241e28c2236b"), one of which (Surface - System - 14.502.139.0) claims to "improves USBC performance", the same issue can be reproduced, as pointed out by @[JDPurcell2 and @Hanxxxx
Update on 3 Sept 2021:
I'm elated to share that after the 31 Aug 2021 Updates, which "addresses the system hang and shutdown issue", my USB-C port works well.
I've tested it 3 times, and then the Laptop can restart normally, after which the USB-C port still works normally.
