  1. A note on the StarTech PEXUSB3S44V. I recently picked up two on eBay and they turned out to be different hardware revisions. One works great with passthrough and the other does not. Unfortunately it's the newer (and more readily available) version that has problem. I have (3) Windows 10 guests under ESXi 6.0. Each guest gets an old Radeon 240 and a single USB3 controller from the PEXUSB3S44V. PI40202-6X2B -> Recognized by Windows 10 guest, works great PI40202-7X2B -> Recognized by Windows 10 guest, throws code 10 I confirmed the 6X2B card worked then shut the host down and swapped the 7X2B into the same PCIe slot. I made sure both cards had the same PCI ID's, firmware revision, etc. The 7X2B caused the guests to throw code 10. Shut it down, swapped the 6X2B back in and everything worked fine again.
