Hi guys,

I was and still am dealing with a user who if he/she now enables verifier, the system freezes rather than BSOD'ing. The first time I instructed to the user to enable verifier, the flagged driver was iusb3xhc.sys which is the Intel(R) USB 3.0 eXtensible Host Controller Driver. The second verifier enabled dump faulted BitDefender. I instructed the user to update the host controller driver from Intel's website, and that was done. After that though, the user now reports that devman says that the Universal Serial Bus (USB) controller as not installed properly.

Not quite sure what to tell the user to do next. Is that a chipset driver issue, or a standalone driver issue... what needs to be reinstalled, etc.

Thanks.
 
Have they totally uninstalled all their motherboard's chipset drivers and reinstalled the latest version? Remember that for OEM PCs you may have to default to using whatever the OEM provides. Don't forget the BIOS too, btw.

I personally don't know what would cause Driver Verifier to freeze instead of BSOD unless there's some sort of race condition it's triggering that's caused from the extra checks it does which it isn't able to detect (Windows 8 DV does a lot better detecting race conditions). There's also the possibility we're dealing with some faulty mobo which is showing signs of failure through the USB.

Other than that, without some sort of crashdumps or the like, not exactly sure. Are they using any software that has anything related to USB devices or some sort of "USB enhancement" software like Ai Charger?
 
Verifier pointing to more than one cause suggests that Verifier isn't identifying the correct fault.
Could be another driver, could be hardware, could be Windows.

Disable USB 3.0 in the BIOS (if there's no separate 3.0 setting, disable all USB in the BIOS)
Then test for stability (both with and without verifier).
 
Yes, that would be a problem.
But OTOH, without a keyboard/mouse he wouldn't have to worry about USB issues! :hysterical:

He'd have to pull the CMOS battery to reset the CMOS (since the USB keyboard wouldn't work to get into the BIOS)

Thanks Wrench97!

I learned that a couple of winters ago on a snowy night.............Disabled the USB ports and just as I selected Save and Reboot I realized it was a USB KB and the only PS/2 KB I had was in the Garage, after shoveling my way out I thought it best to always keep one in the house:r1:
 
Thanks for all of the responses, guys. Will provide an update whenever I have one.

Regards,

Patrick
