I have the 34" Ultrawide Thunderbolt 2 monitor 34UC98-W.  I have a thunderbolt cable from Mac Computer to thunderbolt 2 input on monitor.  But the USB downstream ports are not recognizing any devices.  All was working recently, but now they are not.  The USB ports will power or charge external devices, but they will not recognize them.
