Consider the following scenario:

• You connect a USB 2.0 high-speed device to a USB port on a computer that is running Windows Vista or Windows Server 2008.
• The device is successfully detected by the computer.
• You repeatedly disconnect the device from the computer and then connect the device to the computer.

In this scenario, the port no longer works and the device is not detected by the computer.

This problem occurs when the USB selective suspend setting is enabled in the Power Options dialog box.

Consider the following scenario:

• You enable the USB selective suspend” mode on a computer that is running Windows Vista or Windows Server 2008.
• The computer switches from battery power to AC power, and then switches back to battery power.

In this scenario, USB selective suspend mode does not work as expected. Therefore, the computer consumes more power than necessary.

This problem occurs on certain hardware.

Consider the following scenario:

• You have a computer that is running Windows Vista or Windows Server 2008.
• A USB-based CD-ROM drive is connected to the computer.
• An application sends an input/output (I/O) request IOCTL_SCSI_PASS_THROUGH_DIRECT to the CD-ROM drive.

In this scenario, the computer crashes. Additionally, you may receive a Stop error message on a blue screen. The Stop error message resembles the following:

STOP 0×000000D1, (parameter1. parameter2, parameter3, parameter4)

Consider the following scenario:

• You connect a universal serial bus (USB) camera to a computer that is running Windows Vista or Windows Server 2008.
• You plug in and then unplug the USB camera from the computer 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 unplug the camera. Additionally, you receive the following Stop error message:

*** Fatal System Error: 0×000000C4 (parameter1, parameter2, parameter3, parameter4) DRIVER_VERIFIER_DETECTED_VIOLATION

Consider the following scenario:

1. You install a non-Standard Port Monitor (SPM) or non-Line Printer Resource (LPR) printer with a universal serial bus (USB) port.
2. You use the Printbrm.exe command-line tool to export the printer settings.
3. You import the printer settings to another computer.

In this scenario, the printer port for the restored printer is displayed as FILE. Additionally, if you plug the USB printer into the new computer, you are prompted through all steps of printer installation. After the printer is installed, you see a second instance of the printer on the new computer.

This problem occurs on computers that are running Windows Vista or Windows Server 2008.

After you upgrade from Windows Vista Service Pack 1 (SP1) to Windows Vista SP2 or from Windows Server 2008 to Windows Server 2008 SP2, your computer crashes frequently and you receive the following stop error message:

Stop 0×000000FE (parameter1, parameter2, parameter3, parameter4)
BUGCODE_USB_DRIVER

This problem usually occurs on computers that have NVIDIA chipsets. Additionally, this problem may occur when you perform very basic operations, such as plugging in a USB keyboard.

If you have a USB Streaming device attached to a computer running that is resuming from a Sleep (S3) or Hibernate (S4) state, the system may halt and you may receive a “Stop 0xFE” error message on a blue screen. This error message resembles the following:

STOP 0×000000FE (00000002, parameter2, parameter3, parameter4)
BUGCODE_USB_DRIVER

Assume you connect a high-speed USB 2.0 device to a computer that is running Windows Vista or Windows Server 2008. After you put the computer into hibernation and then resume the computer, the USB 2.0 device is recognized incorrectly as a full-speed device instead of a high-speed device. Therefore, the transmission speed over the USB connection is significantly reduced.

This problem occurs occasionally.

The MIDI application that uses the inbox universal serial bus (USB) audio driver crashes after a high rate of MIDI events occur on a computer that is running Windows Vista or Windows Server 2008.

Consider the following scenario:

• A USB device is installed on a computer that is running Windows Vista or Windows Server 2008. The USB device works correctly.
• You plug and then hot-unplug (surprise remove) this USB device several times.

After you plug the USB device into the USB port in this scenario, the device does not appear in Device Manager. Additionally, the device does not work. If you try to shut down the computer on the Start menu, or if you make additional surprise removal attempts, the system generates the following Stop error message and then automatically restarts:

Stop 0×000000FE (Parameter1, Parameter2, Parameter3, Parameter4)

Notes:

• The four parameters in this error message vary, depending on the computer’s configuration.
• Not all “Stop 0×000000FE” errors are caused by this problem.
