Peripherals no longer work through Elgato Thunderbolt hub after most recent MacOS update

After the most recent update lost my sound bar and web cam, both were connected via USB to an Elgato Thunderbolt hub. External display still works fine, network cable connection works fine, but not USB stuff. The hub is connected to an MBP late-2015 via Thunderbolt cable. Plugged the sound bar and cam into a USB 3 hub, plugged into the MBP via USB — work fine now. Is there a compatibility issue or some other problem working with USB devices via Thunderbolt? Didn't even detect the devices after the update.

MacBook Pro 15″, macOS 11.3

I have seen a different manufacturer of a thunderbolt hub recommend resetting NVRAM to address USB problems, you might try it and see if it helps:

Surprisingly enough, this has helped, thank you! I've been running on this hub without ever installing any software for it at all for years, I didn't even realize there was something to install. But, after installing the software from the provided link and a reboot - now the hub can chain USB devices again. Thanks, Leanne!

Thanks. Actually, that's the standard Apple "first aid" response to any problem. With Windows it's "Have you tried rebooting?", with Apple it's "Have you reset NVRAM and SMC?" And yes, I have. I have the key combinations for that on a Post-It note on my monitor :-) Didn't help...
