Dell Xps to Dell Docking Station Blue Screens

You dump file says the faulting module is:

Probably caused by : oz776.sys ( oz776+2b16 )

This is a driver that belongs to O2Micro Card Reader (I Googled that part).

You can do some Google searches for oz776.sys yourself and see what problems other people have had with BSOD and this driver.  I did not see one that had a happy ending - the threads just seem to peter out or people give up.  You may want to read through some of them yourself and see if any sound like your problem.

If you go to the Dell WWW page, select your system, choose to look at Drivers, look in the Security section, there is a listing for the O2Micro Smart Card Controller.

I would check your installed version in Device Manager (Start, Run, devmgmt.msc) and if the one on the Dell download page is a later version, install it.

I don't have your environment and never will so I am just suggesting what I would do if it was me.

Maybe somebody else that has your environment or actually fixed the problem before will have another idea


Don't guess what the problem might be - figure it out and fix it. I need YOUR votes and points for helpful replies and Propose as Answers. I am saving up for a pony!

Thank you for the reply.  Yes, I've done all of that (serveral times) on and off over the last year or so, and have yet to find the happy ending, or the driver update that will take care of the problem.  The best thread that I've found was on here, and it just fizzled out over the Summer, so I was hoping to revive it with the post.

Somehow I had the impression/feeling that you have already done some looking...

Are you on the latest driver offering from Dell?  If you are not sure, I can help you figure that part out.

You have some USBhub stuff in your dump file as well but that doesn't mean it is afflicted, so you can check Device Manager (any yellow or red marks) and the Event Log after a failure for any errors and maybe more clues.  Maybe you will be the one to finally figure it out.

The O2 page is here but I don't see a Support option, but you could send them a query.  They may know exactly what the problem is:

http://www.o2micro.com/prods/prod_smartcard.html

You could also post out in the Dell forums if you haven't already, but I find little useful information out there (sometimes there is some good stuff).  Dell usually suggests you reformat and reinstall and "see how that works",   but some other human beings out there may have figured it out in the Dell support groups.

Looking for happy endings is a good thing.  Me: "Find and follow some advice (if you can) where there is a happy ending and is not just a bunch of trying things that might work maybe".

Rotsa ruck!

That's easy... Microsoft have yet to fix their power management to prevent it from calling the leaving USB-IDLE state TWICE.

Had the exact same bug...  It ocurred at usbhub!USBH_HubCancelIdleIrp+2d, but was caused by various poorly written drivers.  In my case, it was the USBHUB module (usbhub.sys)

In my case, it occurred when the lid is closed, or when the blackberry is pulled (or in your case, the docking was disconnected).

That's a USBHUB.SYS bug.

No preventative coding were put in nt!IoCancelIrp to prevent the Power Management from calling the usbhub!USBH_PortIdleNotificationCancelRoutine TWICE.

In your case, it is most definnitely the oz776.sys driver.  In my case, it is the USBHUB.SYS.
