I built a nice machine for my wife with a Gryphon Z87 (i5-4440S, 16GB 1866 RAM, Windows 8.1 Pro 64-bit fully up to date) and put it in a Thermaltake Urban SD1 case. There are two USB 3.0 spigots on the front panel. These seem to work OK - except if I plug in a second USB 3.0 memory stick - it won't recognize the second one. It recognizes either one in either spigot, it just doesn't like a second one being plugged in. Is it the W8.1 built-in driver? The internal cable? The phase of the moon?
Ideas?
Bye.
