I have a 16" MacBook Pro M1Pro and am using a couple of external Thunderbolt 2 hard drives connected using Apple's TB2-TB3 adapter. The disks will not mount using the Thunderbolt4 port closest to the MagSafe Power connector! I have tried the other two Thunderbolt4 ports and the disks mount fine. I also tried plugging in a USB-C flash drive into all three ports and it mounts right away, as well as an external monitor using USB-C.
I believe I read that the new MacBook Pros have a separate controller for each of the three ports, although the USB-C peripherals mount fine using all three. Any ideas?
