I am using 3 displays. All of the 3 external displays work on other computers + USB devices, but the thing is my GreenCell USB Hubs aren't working either on my M1 MacBook Air.
I think several people are confused because it seems a lot of people are reading you using hub/docking station/dongle interchangeably in reference to all these devices you've tried. I've gone back over the past four pages trying to see which one is your main complaint and I still can't decide if it's the dell you link or the greencell.
As for the greencell, the page for this device says
(for M-series processors, macOS Big Sur 11.2.2 to 11.6.1 version required), as I mentioned before, but i'm still not sure if that's the greencell device you're talking about.
Yes sir,
I am on macOS 12.1 and I was hoping the new update would fix the issue, but it didn't.
I think my only chance is to downgrade back to Big Sur as well… I know macOS 12.2 is coming out soon, but there's a possibility it won't be fixed in the next release either.
There are more people with the same issue, so I'm pretty sure it's on Apple's side. Macs used to be machines that just worked. I'm so disappointed in Apple for real.
My docking station recognises the displays, but not any USB devices. The same goes for GreenCell USB Hubs that I bought for testing. Displays all just work fine, but not the USB devices. Even my headphones stop charging. I didn't have the same problem on Big Sur or High Sierra or Windows 10, so I'm sure the hardware is fine.
It sounds like you're frustrated that equipment that previously worked no longer works, whether it was software or hardward incompatibilities. Honestly even if you do assign Apple blame, I hardly see how they are the sole bearer of it. Hate to sound like a simp for Apple but still. Again, only going off the two devices you semi-mentioned, both pages explicitly state the hardware you have isn't guaranteed to be supported. (see below)
I bought GreenCell USB Hubs for testing, because they were cheap. The very same GreenCell devices work with Windows though. I do believe those are bad, because they were like $15, but the main issue is my Docking Station.
Buying things because they're cheap while cost effective often leads to more headaches than it's worth. I'd check compatibility with your known devices instead of getting lured by a good deal.
No, because the other Docking station didn't work either (the one I tried at the office) nor do the USB Hubs.
You've mentioned docking station and hubs (plural) so we're all not sure if they're the same or different ones. Links to specific ones for any troubleshooting would be helpful for anyone who has specific hardware experience. Personally I'm knew to all this USB C stuff, but i know with all the common ports, it's actually lead to a lot of confusion because cables and supported protocols are all over the place, in both Mac and Windows systems. The problem with a universal standard is that it can't do everything for everyone all the time.
I use this Dell Docking Station and the other one was Dell as well, but I didn't look up the model.
The very same Docking Station worked on Big Sur. It works well on Windows 10.
Funnily enough, when I reinstalled the drivers yesterday it worked perfectly and after I restarted my MacBook it ceased to work. The displays work, the USB devices do not.
I'll downgrade to Big Sur and will let you know if it still works on Big Sur, but then there's also a possibility that maybe something happened to the OS and it needs to be reinstalled? I've read such instances on this forum ( I couldn't find it anymore, but I swear someone on this forum said that they reinstalled macOS12 and now their docking station is working).

That dell docking station's manual
here found
via this page lists very specific resolutions/refresh rate combos that are compatible. That could be one issue here, as you might be trying to push too many pixels. Triple displays specifically here are listed as " 3840 x 2160 / 30Hz 2048 x 1152 / 60Hz 2048 x 1152 / 60Hz" for DP HDMI 1 and HDMI 2 respectively on page 3. Settings other than this may overload it. as well the minimum hardware requirements on page 5 are

So while it worked with Mac before, it is in no way guaranteed to.
The user guide is from 2017, so there's no telling what's changed in 4 years.
Hopefully if it was working in an acceptable state and you can restore it to that state this weekend, your problems will be solved. As for Apple releasing an update that then makes something incompatible, again I argue the other manufacturer is just as much at fault as Apple. Designing for every use case and instance-- I can't even begin to imagine how hard it is. And maintaining backwards compatibility for everything inevitably either limits progress or drives up price. There are always trade offs to everything.
Again, understand why you're upset, but coming here without specifics and bringing in other anecdotes with situations that might not exactly fit yours doesn't help anyone help you. Granted, many posters don't seem to be behaving in the spirit of wanting to help, but in their defense it sometimes also seems like all their previous advice has been ignored.
Basically a lot of people in the forum are going to come back to generally agreeing with this quote from above:
What’s your point? It’s an issue with 3rd party hardware that’s not certified.
Anyway, hopefully the roll back works OP
