Thunderbolt/USB-C problems

[jay968]

Sorry if this has been discussed before but I cannot seem to find it:

Using Mac Mini 2024 M4, Caldigit TS4 hub, Apple Studio display attached to the Mac Mini, 18" generic LCD panels as second monitor attached to the TS4, Satechi Bluetooth (and wired) keyboard, Apple Magic Mouse, Canon flatbed scanner, Crucial external 2tb SSD.

EVERYTHING was fine until a couple of days ago but all of a sudden the keyboard (tried 2 different ones actually...the Satechi and an old Logitech Windows keyboard), and flatbed scanner, no longer work when attached to the TS4. Both of my monitors still work fine, the external SSD usually does but sometimes is not recognized when I reboot.

Everything (keyboards, scanner, SSD) USUALLY work fine when attached to the Mac mini itself but the Satechi keyboard sometimes is not recognized upon reboot.
I've tried different cables, different thunderbolt and/or USB-C ports and nothing seems to make any difference.
The ONE thing that I have changed in the past couple of days was that I upgraded to Sequoia 15.4.1.

Is THIS the culprit?
Are there any known USB-C and/or thunderbolt port problems with this release?

Update:
After turning both the Mac mini and the hub off and unplugging them both for about a half hour, everything seems to have come back to life after turning all back on again.
Apparently a proper reboot may have been all that was needed.

You´re lucky!
I don´t get USB working properly. My audio-interface, my webcam do not work, all hubs do not work. The hub in my monitor does not work, too.
Thats apple in 2025

that's your apple experience in 2025. have you tried calling them for help? 🤔

Yes of course this is MY experience.

Have you ever needed their help. I had 2 experiences with the Genius Bar - it was really creepy. There wasn't a single person who really had anything on it. But they kept saying that Apple Devices never actually have anything like that. You have to explain the simplest things to them. Idiots.

I always make a point of not installing their updates. That would be the only solution. But I didn't read anything about the problems this time either - it wasn't until I got it myself that I knew there were any.
