For those with USB 3.0 failure issues, Broadwell / Yoga 3 (maybe others)

Just solved an issue with my Yoga 3 (Win 8.1, 64-bit) thought it might help others if I share what happened...

 

Symptom:

 

USB 3.0 and/or USB 2.0 port(s) stop working, related hardware on the USB 3.0 (touch screen, card reader) also fail. I noticed this after letting the Yoga go to sleep with a USB memory key still attached earlier today.

 

Observation:

 

Device Manager shows an error or warning against the xHCI (USB 3.0) hub (Code 10 or 12 usually.) Un-install/re-install doesn't fix it, reboot doesn't fix it, reseting BIOS settings doesn't fix it.

 

My Fix:

 

  • Change Device Manager View to "Resources by type"
  • Open up "Interupt Request (IRQ)"
  • Skip the "ISA" entries and scroll down to to the "PCI" ones.
  • Find the failed USB 3.0 hub entry
  • Check its desired IRQ number (e.g. 7)
  • Disable any other devices on the same number (I found some vague "Intel Device")
  • Reboot
  • USB should be back!
  • Re-enable device entries

For the old ISA IRQs you wouldn't really want to share them between devices but, even though there are loads more available on the PCI bus, you will see lots of devices on a single PCI IRQ line. Why did Windows suddenly flip over this? Answers on a postcard please Smiley Happy

 

Anyhoo, hope this saves someone else time and energy Smiley Very Happy

Sounds like the USB device prevents the system from auto assignment of PCI Bus attachment. I would be interested if it re-occurs with any USB item, or just the one USB key.  Also - as a side note -  have you tried using a differnt OS (Windows 7 or Linux) to check it out?

Have tried this for the same issue on a Yoga 2 but it did not work.

More exactly, there aren't any same IRQ number for the other devices (mine was -5).

Thank you though.
