I also tried to reset PRAM and SMC, just for a what if. When he powers up his computer, the SSD drives are detected immediately as normal. Anyway, he does not have any such problem with his system.

Otherwise, he has the same identical SSD drives as I do (OWC Mercury Extreme Pro 6G). So he had to buy an Apple adaptor cable (Thunderbolt 2 to USB-C). And his Blackmagic Multidock is the older version, with the Thunderbolt 2 connectors.

Except that his iMac Pro is running the previous OS X High Sierra. I should also mention that a friend of mine has an almost identical setup. I plugged it into the iMac Pro that was there on display (which was running OS X 10.4.6 Mojave), and the same thing happened. Today, I took my Multidock down to the local Apple store. The SSD drives only are detected if I unplug and re-plug the USB-C cable from the back of the iMac Pro, while the iMac Pro is up and running. I have repeated this process countless times and it's the same problem each time. However, when I tried to unplug the USB-C cable (from the back of the iMac Pro) and then plugged it back in, suddenly, the SSD drives appear. They don't show up on the desktop, nor do they show up in Disc Utility. With everything connected and plugged in, when I power up my Imac Pro, it does not detect the SSD drives. And my USB-C cable is plugged into the 'A' connector. On the back of the Multidock, I have the switch in the '4' position (to use all 4 slots on the same A bus). In the Multidock, I have 2 SSD drives, OWC Mercury Extreme Pro 6G, inserted in the first 2 slots of the Multidock. I connected the iMac Pro with the Multidock via USB-C cable (the cable was bought at OWC Macsales, for what it's worth). I also have a new iMac Pro (2017 model), running OS X 10.14.5 Mojave. I just purchased the brand new Blackmagic Multidock 10 G.
