Ok - so this wasn't just an external web cam issue for me, as I first thought. It appears that certain USB Hubs and cables are no longer working well with Monterey.
My setup used to be USB3.1gen1 cable to Dell 4k Monitor (with built in USB 3.0 Hub) > USB 3.0 cable to Dell D6000 Dock > USB-C (not sure of the spec) cable to the Huddly IQ 4k WebCam.
- It appears the USB dock on the Dell monitor is no longer running at 5Gbps on Monterey.
- But also certain USB-C cables that used to work with the camera (or other devices) plugged in directly to the MacBook now no longer work either. This includes the genuine apple USB-C cables that I had to hand.
I swapped out all the cables with brand new USB-IF certified cables and changed my setup so the D6000 dock is now directly plugged into my M1 via USB-C 3.1gen1 and the dock then connected to the webcam similarly (slightly annoying as now I have to plug in two cables, rather than one) - the camera now connects at 5Gbps and is working.
I have tested other devices too and they had also dropped from USB 3.0 'superspeed' 5Gbps or USB 3.1 (5Gbps or more) down to old school USB speeds of ~480Mbps. The 4k USB-C camera just didn't work connected at those speeds.
So about £50 spent on cables and still not back to where I was, but at least my setup works again in this new configuration.
No idea why the hub in the dell monitor isn't playing ball.
Hi,
After upgrade to Monterey, latest public beta (21A5506j), PD over usb-c from my monitor (Philips 346P1CRH/00) doesn't work as well.
Apple please help!
Looks like most comments here are with MacBook and the M1. I have a been running a duel monitor set up with my MacBook Pro (intel) for years without issue on the MacOS Beta program. It wasn't until I just upgraded to release 8 that the monitors are no longer detected. I have not been able to find a workaround so any help would be appreciated.
PD (Power Delivery) over USB-C also stopped working on my MBP 2018 after updating to Monterey (12.0.1). I use a Philips 346P1CRH. Everything was working flawlessly with Big Sur.
