image capture broken by osx 12 update

After update to osx 12.0.1 on my Mac mini M1 the Image Capture can't connect to my Brother MFC-L2731DW scanner anymore. I'm getting "Failed to open a connection to the device (-21345)" error.

Printing works.

I did a "Reset of the Printing System" (hold ctrl, and click on the printer list) and added everything again using Air Print. No errors here.

If I use the Brother print & scan tool, i can normally use the scanner.

It seem to be an issue with the osx update.

Any ideas?

PS. osx 12.0.1update broke my USB-C hubs as well.... USB ports are dead.

Mac mini, macOS 12.0

No the IPv6 was disabled. After enabling it the scanner is working again.

Regarding the usb hubs It's been reported 6 months ago... and still they decided to release the 12.x update

Have you powered off and then back on your router and restarted the Mac?

Yes, some hubs do not work after upgrading to Monterey. See:
