We have several Plugable products working on 2 separate Thinkpad Carbon X1 Touch PCs:
USB 3,0 4-port hub
USB 2.0 4-port hub
USB 3.0 Gigabit Ethernet Adapter (plugged into the USB 3.0 hub)
When we have a USB 3,0 external hard drive plugged into the 2.0 hub, it works fine; each PC does its Acronis backup just fine.
When we plug the external hard drive into the 3.0 hub, it drops connection once in awhile, like once every day or two on either PC – quite annoying during nightly backups!
I did a bit of research into this, and it may not be the problem with the hubs. After all, our 3.0 Ethernet Adapters work fine continuously in the 3.0 hubs. The problem may be with hard drive connections (voltage, kind of connection??) with 3.0 devices? I have found several places where to set that the USB 3.0 driver should NOT sleep, but this has not helped.
