The uas message is again from device 6:0:0:1 as before, even though the disks have been swapped. IOW the issue definitely comes from the dock, not from the physical drives themselves.
I don't know if it's coming from the dock's usb chipset or the usb-sata adapter on the drive. That adapter has a chipset on it also. These are exactly the sorts of problems often resolved by putting both drives on a USB hub, and then the hub into the dock.
I don't think the drives have internal USB-SATA conversion. These are internal SATA drives, so I assumed any USB stuff was being handled by the dock.
In any case, I tried plugging the dock into a USB-3 hub, but it made no difference.
I'll consider taking this to the linux-usb list as you suggested earlier.
