Random BSOD, DRIVER_IRQL_NOT_LESS_OR_EQUAL, usbser.sys

Hi All.
Hope someone can help as I'm kinda running out of ideas. I have a new PC build with Win 7 x64 running in a retail environment. Once every few days the system blue screens often when its not even being used. System has latest BIOS and device drivers. Have run a memtest , check disk, windows System File checker and nothing found. I figure it has something to do with one of my USB device drivers but just which one and how. Attached is Diagnostic file. If someone could point me in the right direction it would be much appreciated.

System Specs:
Win 7 Pro x64
Gigabyte GA-H81M-S2PH MATX LGA1150 MB
Intel Core i3 4130 3.40GHz 3MB LGA1150
Adata 4GB Premier Pro DDR3L 1600 DIMM
Star TSP143 ECO USB Thermal Receipt Printer

Hi punga.

Upload the list of all the third party drivers Using NirSoft DriverView :

• Download and execute Driverview
• View > Hide Microsoft Drivers
• Edit > Select all
• File > Save Selected Items
• In the Save dialog, Set the path to desktop, Put "Driverview" in the name field, and save.
• Zip the .txt file and upload it.

We need it because the crash dumps are not providing enough information in them.

I was searching for the information about any USB modem that is in use. But the files are not saying anything about it.

The USB driver is up to date.

Code:

Description       : Intel(R) USB 3.0 eXtensible Host Controller Driver
Version           : 3.0.0.16
Company           : Intel Corporation
Product Name      : USB 3.0 Device Driver
Modified Date     : 21/02/2014 5:56:14 p.m.
Created Date      : 11/06/2014 4:26:20 p.m.
Filename          : C:\Windows\system32\DRIVERS\iusb3xhc.sys

It is odd that still the USB related BSOD is triggered.

In this situation IMHO it is better to enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.
