After applied the June 2021 Firmware Update for Surface Laptop 3, this issue occurs:
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
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.
Update on 24 July 2021:
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.

Thank you for reporting the issue. A fix is available through Windows Update. For more information about updates for your Surface available through Windows Update see the Surface Laptop 3 update history page.
Marking as "Answered" for now to raise visibility.
Thank you, Roboal111. I've just checked my update history and don't see any firmware installed nor available for download on my machine.
Are you able to attach a picture of the update you received so I can see if I maybe got it previously?
I'm registered on the Release Preview Channel.
New firmware was pushed out to me this morning on the Retail channel. I hope this fixes this issue as it has been going on far far to long.
I’ve tried the Windows Insider firmware update, however it still occurred sometimes.
I charge my SL3 via usb type-c with a 60W power adapter. Sometimes when I unplug the type-c port charging cable, SL3 screen freezes. Nothing but pressing power button for 20 seconds to force shutdown could work.
I hope these type c problems could be fixed soon.
To be honest, the price of surface series is not cheap, I’m really disappointed at Microsoft surface to have such quality.
( I have used Surface since pro 5 then pro 6, go and now SL3)
I am still left with Wifi speed issues.
I had the exact same issues. After uninstalling the USB drivers and rebooting the system, the Surface Laptop 3 was bricked. The device was only 2 months old and the issues started immediately after the firmware updates in question. It was working 100% fine prior to the firmware updates.
Microsoft swapped out the device for a brand new laptop. I switched on the new machine, ran Windows Updates and the same Unknown USB Device (Port Reset Failed) started to occur, and the only way to reboot the machine was to hold down the power button for 20 seconds.
I managed to resolve the issues by switching off the Allow the computer to turn off this device to save power options in Device Manager. for multiple USB devices, as well as switching off Stop devices when my screen is off to help save battery. If you're having problems with connected devices, clear the checkbox located in Settings > Devices > USB
I've just joined the Windows Insider Program and received the recommended firmware update which apparently fixes things. I was then able to revert all my manual changes and the system is stable when plugging the USB-C hub in and out.
The one issue I'm still experiencing is that my internet speed goes to a snail's pace when a USB hub is plugged into the machine. The USB hub doesn't have an ethernet port, so I'm unsure as to why it is affecting my wifi speed.
I'm running 100Mb fibre, which works perfectly when the USB-C hub is not plugged in. When it is plugged in, I can barely load webpages, let alone download files or stream video. Sometimes, it seems to completely lose DNS and I get "webpage cannot be found" errors, and Windows shows the wifi as being "disconnected" because it can't resolve DNS. The max resolution I can stream via YouTube is around 480p with buffering. When the USB-C hub is disconnected I can stream 4K without buffering.
I've plugged my mobile phone into the USB-C port, to see if the issue persists across multiple devices, but my wifi worked perfectly fine when the phone was attached. I unplugged the phone, plugged the USB hub back in and the wifi immediately started acting up.
