So, I was originally having some issues with updating an iPhone 6 last week (http://www.tomshardware.com/answers/id-3518220/weird-issues-iphone-updating.html), & was initially confused as to what might be causing it. However, now I'm wondering if there's maybe something else going on. I could see a problem with the iPhone causing it to lose connection to the motherboard (& causing the 2-hour hassle with updating & restoring it)...but that wouldn't explain other devices having the same connection issues:

  • ■ A 2nd iPhone (the one that flawlessly went through its update on Friday) lost connection
    ■ USB 3.0 hub lost connection
    ■ Two separate USB mice lost connection
    ■ iPod Touch (4th generation) lost connection
In every case, it was followed by an error message about failure to recognize the last USB device that was plugged into the port -- even if they were devices that had been plugged in since it first booted up (as opposed to devices just recently connected). I was able to solve the connection issue by:

  • ■ Switching the USB cable to a different USB port. However, invariably the device loses connection again on the new port after a varying period of time (the more data sent over the port, the shorter the time). And it didn't seem to matter if it was a USB 2.0 or 3.0 port, & didn't matter whether it was a "powered" 3.0 port or a non-powered one. Also,
    ■ Rebooting the PC would "reactivate" the nonworking USB ports.

However, even the reboot seems to be a temporary fix, as it hasn't gone 100% away yet.

Just to be safe, I reinstalled the USB drivers from Gigabyte's website, but that didn't seem to affect it.

I'm not 100% sure what's causing this, but I'm leaning towards 1 of 2 possibilities:

    ■ For whatever reason, a recent Windows update has futzed something up. However, since in general I've been leaving my PC turned on 24/7, & prior to having to reboot this past Sunday it had probably been at least a week since the last reboot (if not longer), I'm not sure how an update would have affected it. And I can tell that the system didn't reboot on its own, as I use AMD Overdrive to monitor my temps, & I don't have it set to start automatically with Windows.
    ■ Despite my careful monitoring of operating temperatures, my resistance to any overclocking that might stress the motherboard, & just general care to make sure that this desktop (which is our primary PC, storage site of all of our photos, & used quite often by my wife to work on her lesson plans) continues to function without a hitch, something has happened/is happening to the system that means it might be time to consider replacing it. I would be rather surprised, however, given that a) this is part of Gigabyte's Ultra Durable line, & I didn't think I'd had it for that long.

Although the full specs are in my signature, I'll include them anyway:

  • ■ CPU: AMD FX-8320 (stock speeds & cooler), thermal margin is 40-50C @ idle, 10-20C when operating
    ■ Motherboard: Gigabyte GA-990FXA-UD3 (revision 4.0)
    ■ OS: Windows 10 Professional (64-bit)
    ■ RAM: 8GB DDR3-1333 (2x4GB sticks)
    ■ PSU: EVGA SuperNOVA G2 850W
    ■ GPU: MSI R9 380
    ■ Storage: Samsung 850 EVO SSD (250GB) primary, WD Black 1TB & Blue 1TB 7200RPM HDDs (secondaries)

We have practically the same setup, in all these 6 years that I've owned the Gigabyte GA-990FXA-UD3 (rev 4.0) I haven't had a single issue with it.

Three things come to my mind as possible causes for your issue:

- Driver issue, even though you have already reinstalled the USB drivers some corrupted .dll or another critical file might have remained and is once again being used/ causing conflict with your OS updates.

- Static, I've seen some computers having weird USB issues due to static, though most were on really old systems with so much dust accumulated, once cleaned the problem went away.

- Can't really say this is the issue, but with the mobo drivers there's a driver/software to make your USB ports to deliver more power to...

- Can't really say this is the issue, but with the mobo drivers there's a driver/software to make your USB ports to deliver more power to charge faster cellphones etc even if your PC is turned off. I've never installed it, but if you have maybe this got corrupted and is causing the problems you're having?
