10.15.6 made changes in how USB devices worked, see the changelog. And then of course there was the supplemental update to 10.15.6, that actually reverted to an earlier kernel. Presumably those changes were not reverted in 10.15.7, so if 10.15.6 is causing an issue, 10.15.7 will still cause the issue.
Got a tip for us?

MBP 13 2020 won't recognize USB devices from CalDigitTS3+ dock after sleeping and connecting to the dock, and after unplugging the dock it crashes

I don't use any USB device, I connect the 2020 MBP 13 directly to a LG Ultrafine 5K via the Apple Thunderbolt 3 cable, that's all, no more external devices connected to the MBP or the LG Monitor, nonetheless when I unplug the monitor from the MBP it will crash with a Kernel Panic error.
What is the Boot ROM version on your computer? You can check that in System Information, Hardware section, If iBridge start with 18. that is the Big Sur firmware, if it is 17. It is the Catalina firmware, I found that the problems happens to me with 18. Firmware, because I had installed Big Sur, then went back to Catalina, and the firmware doesn’t get reverted back to a Catalina firmware.
It seems the issue is fixed with the latest macOS Big Sur Developer Beta 10, released today, I have done some initial tests and no panic errors so far.
hi @brosenz , let us know please is Beta 10 of Big Sur does have the issue resolved please. If the problem was really in ibridge firmware, i could try to install into separate partition OR upgrade and then rollback via timemachine!
Thank you !!!
At least for me the problem has been fixed with Big Sur Beta 10, I initially installed it on a separate partition, did extensive testing, when confirmed the issue has been fixed, I deleted the Catalina 10.15.5 partition.
hi - I installed Big Sure beta 10 in separate partition only to get firmware/iBridge upgraded. I have too many apps that i use daily o/w some have reported incompatibilities with Big Sur so I wanted to stay on Catalina (10.15.7) and only get the 'firmware' upgrade.
However, that did not fix the issue for me (Thunderbolt dock).
1. Boot Catalina, verify that firmware version ( Boot ROM Version: 1554.40.33.0.0 (iBridge: 18.16.12402.5.2,0))
2. Put Macbook Pro 2020 to sleep
3. 30 seconds later disconnect the dock
4. 30 seconds after that connect the dock
5. USB devices and even (that is new) monitor NOT detected and are missing
6. Didn't wait much lunger to test, just rebooted and am working from it now as it is ...
I hope/expect ? that apple will release soon some 'supplemental' update to 10.15.7 ... but I don't think anyone knows...
PS. Don't recommend to anyone to do the above. With Big Sur 'firmware' Catalina will not recognise dock at all (just do a fresh boot w/o connected to anything adn then dry to connect to a dock). Only way is to connect and reboot.

In the last week I have tried two different 13” MacBook Pros and have had issues with both through my Caldigit TB3+ Dock. I have used the dock previously with. Mac Mini and 16” macbook Pro without issue but with the 13” I have had issues with freezing and with one I cannot get any video through the DisplayPort interface at all.
Maybe Macrumors can consider making an article about this, like last time with the USB issues? This problem is actually worse, it crashes the mac - wipes your unsaved work, does an automatic SMC reset, and is just downright unacceptable.
Please, spread the word, make an article, feel free to reference the thread I made in Apple forums: https://discussions.apple.com/thread/251654275
"I have this question too (375)" and 12 pages about the same problem.

it would have been nice if this method had worked. But you did not test your BS installation if the problem is fixed? Would have been great to hear another one confirming that it is fixed in the newest update (not that I don’t believe the person reporting it here, but the more evidence, the better).
you're right @Jochheim, I am sorry - but sadly, it is my working laptop and issue was aggravated by the fact that with installing Big Sur on the same SSD (additional partition) upgraded firmware and my Catalina started working extremely poorly with thunderbolt dock (wouldnt recognise it at all unless it was plugged in when booting, would not recognise monitor etc). So i went with Apple Configurator 2 on another macbook pro and connected via usb-c cable to restore 'original' firmware ... now my Catalina is running as before (standby no good with the dock) but at least it works.
If i had loads of free time i would've done what you suggested and shared with everyone.
Update: 6 days with BS Beta 10, no crashes 🤞
I'm so glad I found this thread. I thought I was going crazy. Everything I see about USB issues says the problem was fixed with 10.15.6 but I'm on 10.15.7 and having the problem. At first I thought it was a faulty dock and the manufacturer sent me a new one and it still has the problem.
I've been not-so-patiently waiting for Big Sur hoping that it'll fix the problem, so I'm really happy to hear the Beta 10 is workig well for some people.

I feel bad for dock brands that got so many returns due to Apple's negligence and refusal to admit the problem is with the macbooks, not the docks.
Quite ridiculous, really, but that's how you make trillions

Thankfully I held on to my TS3+. But I wanted to point out, it affects both MBP and MBA. I have a maxed out 2020 MBA with Thunderbolt (Should have went MBP though...) that when I plug in the TS3, nothing shows. When I plug, computer shuts down.
My new workflow is just to shut down completely, plug in the TS3, then boot up and everything works. Hoping Apple fixes this in upcoming update as I'm trading this in for an MBP.

Yes, all 2020 models are affected.
If you macbook never sleeps between unplugging and re-plugging the dock, it should work. If it sleeps for a while, then it must be restarted or it will crash when you plug the dock. JustAppleThings!
To be clear, mine doesn't crash when I plug it in, it crashes when I unplug it. I'll have the computer running, plug in the dock to connect to my Sony A6400 and Yeti mic to do a video conference, and when I check my settings, I don't see a USB camera. I'll unplug the dock, computer locks up for 1 second, fan goes on high, then it all shuts down. I plug the dock back in and power back on and everything works.
I haven't gotten the computer to shut down when I plug it in, only when I unplug it. Like the computer is looking for the camera/mic/DP monitor (Nothing else is plugged in) and when it can't find, it craps itself.
Please, tweet to AppleSupport, open tickets, harass them on the phone, do what you can. This problem should have been fixed one week after the previous big update. Not in months.
Feel free to retweet or DM them.
One user in Apple's forums said they spoke on the phone with Apple and they were told that "The laptop has to be turned off before unplugging a TB3 dock - that's how it is supposed to work". The audacity and untrustworthiness of this brand is extraordinary. Do not accept their lies.

Apple change log suggests just 3 security fixes. So most likely NO.
Installing now. Will know within the hour and post back.
