STOP error 0xFE Windows 7: BSOD after resuming from Sleep/ Hibernation

After reading this post you will be able to fix a STOP error or better called a BSOD error in your Windows 7 Computer. This error might occur when your have a USB streaming device connected to your computer & you put your computer to sleep or hibernation power state.

Error code:

STOP 0x000000FE (00000002, parameter2, parameter3, parameter4)


This problem occurs when using a USB Streaming device with a driver that uses the USBCAMD2 Streaming driver library. Such drivers are not supported for use on Windows 7. The stop message indicates that the USB streaming device driver using USBCAMD2 submitted two IRPs to initiate Isochronous data transfers, both of which referenced the same USB Request Block to describe the Isochronous data transfers. This problem occurs because the USBCAMD2 Streaming driver library does not properly synchronize resumption of Isoch streams upon resuming from a system sleep/hibernate power state.

Possible Resolution

Use of AVStream is recommended over the older type USBCAMD2 driver that is not supported under Windows 7.

The most simple step would be to head over the support website of your Device Manufacturer & Download and Install latest device drivers for your product.

Note: First uninstall the previous driver by going to :

  • Control Panel
  • Programs & Features
  • Locate your device driver program
  • Click uninstall


  • Restart your computer
  • Install the new device driver you downloaded of the support site.

You can also use Windows Update to Update the device drivers

The error was seen in Windows XP & the resolution therein used to be somewhat different than in Windows 7. In Windows XP this error used to occur due to a power setting problem in Windows or incorrect BIOS settings. Though this error occurs in Windows 7 due to somewhat different reasons & similarity only being the BIOS.

Possible Symptoms, cause & resolution

  • You have a old system and you upgraded from Windows XP or Vista to Windows 7
  • Your system is new and you installed Windows 7 for the first time & bam, you have a BSOD ( Stop error )
  • You have a running system, you updated your Windows installation and you get this error.

  • If you have a desktop system, change the motherboard battery & load setup defaults
  • If you have a laptop/notebook/netbook/ultra book, & it has a removable battery, remove it & try pressing the power button without battery & charger plugged in, for a few seconds (10-15 seconds). Release the power button, plug the battery in and check.
  • Another thing you can try is that you can Press DEL/F2/F10 to go into BIOS at the time of system start up & locate the option called ACPI mode/version & set it to the highest value. (example : ACPI 2.0 or ACPI 3.0)
