Many of the reports are from owners of M1-powered Macs, but not all. My devices were working fine prior to upgrading, and I have been able to replicate the issue and narrow it down by testing against a device that does not have Monterey installed. Some USB Hubs work but certain ports on the hub do not, some Hubs do not work at all.įor me, USB-C & HDMI work on the hub, but my USB 3.0 port will only power devices and there appears to be no data transfer. :/Įssentially, Monterey has broken support for a WIDE number of USB Hubs. After updating to Monterey, the video and ethernet works, but power supply is cut off. Same problem as everyone, bought 34' Philips 346P1CRH/00 and everything worked fine on BigSur. Power Delivery (PD) and Video-Connection not working (but Mouse and Keyboard is still supported/working). I have the same issue with my MBP M1 2020 connected with an external Monitor HP S340c. Everything was working flawlessly with Big Sur. PD (Power Delivery) over USB-C also stopped working on my MBP 2018 after updating to Monterey (12.0.1). For some, it's the additional connectivity provided by external displays that no longer works, with the power delivery affected in particular.

In other cases, the USB hubs work except for the power delivery port. Support told me that many people have been complaining about this issue and it will hopefully be fixed in the next patch to be pushed out. I tried to daisy chain the Amazon hub to the Apple hub but that didn’t work either. I used this one I had floating around in my bag and both the HDMI and USB3 ports worked on it. Had a call with Apple support and they said to try an Apple certified hub.

I also replicated this issue on my M1 MacBook Air after updating to Monterey.

I have tried different C ports on the MacMini and different hubs (I have 4). The HDMI port connected to my second screen is working on the hub but none of the USB3 ports are working at all. My USB-C hub has issues with this update. Reddit user Flyersny81 relates their experience: Some of the problems even relate to Apple certified hubs. In other user reports surfacing online, the USB hubs fail to work at all. In some cases, users say the the USB 3.0 ports on their hub no longer work since upgrading to Monterey, while HDMI, USB-C, and other hub ports continue to work as expected. There have been several reports on Reddit, Apple's Developer Forums, and Apple's Support Communities about the issues. Some Mac users who upgraded to macOS Monterey this week are experiencing problems getting USB hubs and other USB-based devices to work properly with their machines, based on scattered online reports.
