Does anybody saw the issue about not working PD (Power Delivery) via USB-C cable when updating MacBook Pro M1 2020 to Monterey?
My MBP is connected only with USB-C to my external monitor (HP S340c) and now, after updating to Monterey, no charging via that connection. Mouse and keyboard is transmitted through the USB-C connection and sometimes, also the video-connection from MBP to the monitor is established. No change beside the update from Big Sur to Monterey done and still losing feature of Power Delivery via USB-C and video-connection sometimes. p.s. with Big Sur, short before updating to Monterey, everything was working as expected.
What is visible / hearable now?
Precondition:
- Monitor is plugged in with the original powerful power supply.
- Mouse and Keyboard is connected to the monitor.
- (Original HP monitor cable used .. USB-C 3.1 shown on the sticker of the cable) USB-C cable is connected to the monitor and the other end of the cable is waiting to be connected to an other device.
- MacBook Pro (M1 2020) is started and running on battery mode (seen on the battery icon on the menu bar), no other devices connected to the MBP.
Steps done:
- Plug in the USB-C cable from the monitor to the MBR.
- you hear a sound as usual, when connecting a power device to the MacBook Pro
- battery icon changes to the power supply icon
- within less than one seconds, power supply icon changed back to the battery icon
Result:
- no charging done via monitor USB-C connection
- video link/connection randomly established through USB-C connection
- mouse and keyboard working perfectly
Assumption:
- USB-C Hub function not working/supported anymore as worked with Big Sur
Any hints? Does anybody else saw that issue within his/her devices after updating to Monterey?
Thanks already in advance.
Yes I have the same problem with MBA M1 OS Monterey. The USB hub didn't work, only the power hub worked. There are several users also have the same issue, here https://developer.apple.com/forums/thread/683409
I am not sure if we will have any update from apple. Some users said that it worked after switching to other USB hub brand. I think it happened to several types of hub.
