SYMPTOMS

Consider the following scenario:
  • You connect a universal serial bus (USB) camera to a computer that is running Windows Vista or Windows Server 2008.
  • The camera starts streaming content.
  • You disconnect the camera from the computer.
  • You repeat the previous steps to connect and disconnect the camera several times.
In this scenario, system performance is slow.

If you use the Driver Verifier (Verifier.exe) tool to verify the USB camera driver (Usbcamd2.sys), the computer crashes when you disconnect the camera from the computer. Additionally, you receive the following Stop error message:
*** Fatal System Error: 0x000000C4 (parameter1, parameter2, parameter3, parameter4) DRIVER_VERIFIER_DETECTED_VIOLATION
Notes
  • The four parameters in the Stop error message vary, depending on the configuration of the computer.
  • Not all "Stop 0x000000C4" error messages are caused by this problem.

CAUSE

    Collapse this tableExpand this table
    VersionProductMilestoneService branch
    6.0.6000.20xxxWindows VistaRTMLDR
    6.0.6001.22xxxWindows Vista SP1 and Windows Server 2008 SP1SP1LDR
