I just bought a new MBP, it has Mac OS 12.3.1. The same issue - the USB hub doesn't work. it works with the old MBP with old Mac OS. iPhone connects to MBP easily, but the hub doesn't. I have tried different cables for the hub in the best case it's blinking one time per several seconds (looks like the laptop periodically turn on charging for the hub)
