Great suggestion............. but unfortunately it didn't seem to work. When I booted up my Lenovo laptop this morning I was back to the point that after the 15 minute period the USB 3 ports went off again. BUT, this time I couldn't get them back trying to refresh the Intel(R) USB 3.0 eXtensible Host Controller - 0100 (Microsoft) driver as I could yesterday.
It was from that point that I tried your idea. I'm curious, what happens when, after power down, you hold the power button for 5 seconds. My laptop started to boot right away and then turned off right away as you said. I'm conjecturing, if I can back to the state where I could reset the Intel(R) USB 3.0 eXtensible Host Controller - 0100 (Microsoft) driver to a good state, and then immediately do this, maybe I could fix this damn thing.
But at this point, I'm wondering what voodoo chants I might need to include in the process.
'sorry, but I got a bit lost in your description of re-flashing my Intel ME Firmware. You know a whole lot more than I do. And..... I appreciate your time in trying to help out.

Hello Rick8864!
Sorry my suggestion didn't help you out... Check out www.win-raid.com and there you will find info on flashing your Intel ME Firmware. There you can also find the latest Intel MEI drivers too! That forum is incredible! You see Win8.1 is structured differently than 8... Additionally your BIOS may be limiting full Win8.1 drivers... At least that's what I've concluded... Hence everyone's mysterious issues when upgrading to 8.1 on a rig that was only designed for and up to Win8... I blame the OEM and MS for rushing 8.1...
Anyways, I recommend the Intel MEI Firmware & drivers method... Btw, the EC Firmware reset has uo do with resetting the BIOS Energy Config... Thus intended to correct your USB time-out and maintain the settings even after rebooting... Could you please provide me with additional details about your laptop... Do you have any OEM "bloatware" installed? Having to do with Power or specialized system controls and settings? Also try disabling USB Selective Suspend from the Power Plan settings as well as PCI Experess ASPM and Link Power Management to off... Keep me posted and I will do my best to help you resolve your issue!
