Since I get the same symptoms with a WD external disk (with manufacturer supplied USB3 cable), a USB3 FLASH thumb-drive (no cable) and a USB2 FLASH thumb-drive (again, no cable), I’m going with either #2 or #3 here. To eliminate #2, I guess I’ll need a different USB3 interface card. Can someone recommend a good one? This machine has free PCI-X and PCIe slots that I could use. PCI-X slots are (according to wikipedia) compatible with PCI cards. The PCIe slot is “x1”. To investigate #3, I’ve started a different thread on the subject of “What USB3 chipsets are supported by the Jessie kernels?” Thanks! Rick
