Thank you again for your suggestion. Unfortunately, it didn't work. The annoying thing about this failure is that it's unpredictable. It was working for several hours today, and then failed upon a single click. I've searched high and low, and no one -- not Gigabyte, not Intel -- has a driver for Windows 10. The Microsoft driver seems to be the problem (it's very recent) and Windows won't let me roll back to a previous driver.
In the meantime, I found a PCI-e card online that has four ports on the card and a 20-pin port for the case's two front ports. It should be here tomorrow, and it won't be a moment too soon.
I got the PCI-e card installed. Windows found it automatically, but I used the included driver to be sure it's always there. The card has a port to connect to 5v power, and another for the case's onboard ports. So far, so good.
This is the card I bought:

UPDATE: This USB 3.0 card was working smoothly until recently, when it started acting like the motherboard's USB 3.0 ports, i.e., dropping out for no apparent reason. At first I thought the card was failing, but I checked the Device Manager first. And wouldn't you know, Microsoft pushed its own driver for this after-market card -- the same driver that kept the motherboard's USB 3.0 from working properly!
I rolled back to the card maker's own driver in Device Manager, and then set Windows to exclude drivers with Windows Update in the Group Policy Editor. I also turned off that auto app update switch under System / Advanced System Settings. I don't know if both are necessary, but I want to make sure that I have control over updates aside of the OS updates.
This is the DM log collector that we use in another forum for BSOD. It will collect msinfo32, dxdiag, event logs etc.
Please post a zip for troubleshooting:
BSOD - Posting Instructions - Windows 10 Forums
The log collector is useful where there are no bsod as it collects other logs.
Please summarize how you lost USB3.0 and how you troubleshooted to diagnose and then fix the problem.
