The USB-A ports at the back of the LG 32UN880 monitor are not working when I plug the monitor in via USB-C at the back of the Mac Studio. Somehow there's no power going to the hub.
But the monitor hub works when I plug the same USB-C cable to my 16" Intel MacBook Pro.
I don't have issues on the display, just the USB hub not working.
Anyone can shed light why is this happening?
Mac Studio, macOS 12.6
Sorry about that. Anyway, the USB-C cable I'm using is the stock cable that came along with the LG monitor - plugged at the Thunderbolt 4 port at the back of the Mac Studio to the USB-C upstream port at the back of the monitor.
I now know that cable won't deliver enough juice to power my external webcam which is plugged in the USB-A port at the back of the monitor. So I just ordered a Thunderbolt 4 cable and test if that 100W PD feature of it can help with the situation.

you description is too confusing, as there are multiple devices being plugged in multiple places, and many different hubs, both inside and outisde of other devices could be involved.
Please provide a MUCH more crisp description of EXACTLY what is plugged into what using EXACTLY which cables in the case of does work, and what is plugged into what with which cables when it does not work.

Without understanding, my knee jerk reaction is that you have assumed that the USB cable that ships in the box with a Mac is good for anything other than charging. Be assured that cable is a charge-ONLY cable, and can not run any data except a keyboard.If I were King, I would paint it orange so as not to mistake it for a 'real' cable.
