Symptoms

If you quickly and repeatedly insert and remove a USB device, the USB port may stop responding. When the port is in this state, it no longer recognizes any USB device, and the USB device will not work.
This article helps you fix the problem.

Prerequisites

You must use administrative credentials to log on to Windows to perform some of the troubleshooting methods that are listed in this article. If this is your personal computer, you are likely already logged on with an administrator account. If this is a computer that is part of a network at work, you might have to ask the system administrator for help.

Resolution

To fix this problem, use the following methods in the order in which they are listed. After each method, check the USB device to see whether the problem is fixed. If the problem is not fixed, try the next method.
This article also includes a workaround that you can try if these methods do not work.

Method 1: Use Device Manager to scan for hardware changes

Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.
To scan for hardware changes, follow these steps:

Click Start, and then click Run.
Note If you are running Windows Vista, click Start, and then use the Start Search box.
Type devmgmt.msc, and then click OK. Device Manager opens.
In Device Manager, click your computer so that it is highlighted.
Click Action, and then click Scan for hardware changes.
Check the USB device to see whether it is working.

If scanning for hardware changes fixed the problem, you are finished. If this method did not fix the problem, go to Method 2.

Method 2: Restart the computer

If scanning for new hardware did not fix the problem, try restarting the computer. After the computer has restarted, check the USB device to see whether it is working.
If restarting the computer fixed the problem, you are finished. If this method did not fix the problem, go to Method 3.

Method 3: Disable and re-enable the USB controller

Use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager. If you are not comfortable with advanced troubleshooting, try the steps in the 'Workaround' section.
To disable and re-enable the USB controllers, follow these steps:

Click Start, and then click Run.
Note If you are running Windows Vista, click Start, and then use the Start Search box.
Type devmgmt.msc, and then click OK. Device Manager opens.
Expand Universal Serial Bus controllers.
Note You might have to scroll down the list to find this item.
Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
Repeat step 4 for each USB controller that is listed under Universal Serial Bus controllers.
Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
Check the USB device to see whether it is working.

If the USB port recognizes the device and if you can use the device, you are finished.
If this method fixed the problem, you are finished. If this method did not fix the problem, go to the 'Workaround' section.

Workaround

Dell Device Manager Download

If none of these methods worked for you, you can disable the Selective Suspend feature. However, be aware that when the Selective Suspend feature is disabled, all USB host controller drivers (and therefore all USB ports and connected USB devices) in the system are affected. Therefore, your computer cannot suspend any USB devices that are connected to it, and the USB devices can continue to use power while connected to the computer. Additionally, the Allow the computer to turn off this device to save power check box does not appear on the Power Management tab for the USB Root Hub.
This section is intended for an advanced computer user.
You can disable the USB Selective Suspend feature as a workaround by editing the registry. The USB device may become unresponsive because of a race condition in the Selective Suspend feature. The Selective Suspend feature suspends the USB device to efficiently maintain battery power by enabling the computer to turn off the USB device. However, sometimes this feature may not correctly wake up the USB device. Therefore, the USB device is unresponsive when you try to use it.
You might want to disable this feature for server products where power management is not important or required.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 How to back up and restore the registry in WindowsTo disable the Selective Suspend feature, follow these steps:

Click Start, and then click Run.
Note If you are running Windows Vista, click Start, and then use the Start Search box.
Type regedit, and then click OK. Registry Editor opens.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesUSB
If the DisableSelectiveSuspend registry entry is present, double-click it. If it is not present, create the entry. To create the entry, follow these steps:
1. On the Edit menu, point to New, and then click DWORD.
2. Type DisableSelectiveSuspend, and then press ENTER.
3. On the Edit menu, click Modify.
In the Value data field, type 1 to disable the Selective Suspend feature, and then click OK.

Now go to the 'Did this fix the problem?' section.

Cause

This problem may occur because of a timing issue that prevents the computer from detecting the USB device.
Microsoft and the hardware vendors that manufacture the chips that are used for USB have investigated the problem. However, the results were inconclusive because of the intermittent nature of the problem.

Status

Microsoft is researching this problem and will post more information in this article when the information becomes available.

Calman Display Calibration Software directly controls many hardware devices, including light meters, pattern sources, LUT processors, and display devices. The control interface to these devices may be USB, RS-232 serial, or wired or wireless network IP connections.

If the hardware device has a USB interface connection and is connected to a USB computer port, the computer needs to have a device driver installed (unless it is a USB HID device; see below). The device driver tells the computer how to properly handle data communications between the computer and the hardware USB device.

USB HID Devices

The USB Human Interface Device (HID) class is a specification for computer peripherals such as keyboards, mice, and game controllers. A computer doesn’t require a separate device driver for USB HID devices because they are recognized and handled directly by the Windows operating system. Other devices that comply with the USB HID spec are also recognized automatically by a computer and don’t require a separate device driver.

USB HID devices that are supported by Calman include the SpectraCal C6 Colorimeter and the X-Rite i1Display light meters. When one of these meters is plugged into a computer, Windows automatically connects to the meter without requiring an external device driver.

Network Control Devices

If the hardware device is connected to a computer via a wired or wireless IP network connection, the computer does not require a device driver for that device.

Serial Control Devices

If the hardware device has an RS-232 serial connection and is directly connected to a computer serial port, the computer does not require a device driver for that device.

However, since most computers no longer provide a serial port, a serial hardware device will usually be connected to a computer via a USB to serial converter. In that case, the computer needs to have a device driver installed to properly communicate through the USB to serial converter.

USB to Serial Converters

If a hardware device has an RS-232 serial connection, a USB to serial converter is usually used to connect the serial device to a computer’s USB port.

The computer sends data to and receives data from the USB port on the converter. The converter translates that data, through its serial port, to a serial hardware device. The computer requires a device driver to tell it how to properly handle data communications with the USB port on the USB to serial converter.

A data buffer is included within some USB to serial converters. The data buffer improves the reliability of a device interface at high data rates. Many USB to serial converters without a data buffer do not provide a reliable interface between Calman and hardware devices. The USB to serial converters produced by FTDI include a data buffer. The FTDI converters have been tested with all hardware devices supported by Calman and have been certified to provide a reliable interface in all cases.

For more information, see the Calman setup guide for the FTDI USB to serial converters.

Obtaining Device Drivers

Device drivers can be obtained in a number of ways.

The required device driver can often be obtained from the hardware device manufacturer. Device manufacturers may package a device driver with the device or they may provide a device driver download on their device support page.

In cases where the manufacturer supplies operating software with the hardware device, the device driver may be installed as part of the manufacturer’s operating software installation.

If you will only ever connect one or two USB devices to a Calman computer, you may wish to obtain the device driver for your device(s) directly from the device manufacturer.

For convenience, SpectraCal provides a Device Driver Pack that includes device drivers for most of the hardware devices supported by Calman.

To ensure that you have the proper driver, or if you will be connecting a number of different USB devices to Calman, you may wish to download the Calman Device Driver Pack from the Calman Download page to install all supported device drivers on the Calman computer.

Installing Device Drivers

Installing the SpectraCal Device Driver Pack on a Calman computer automatically installs and registers the included device drivers for Calman supported hardware. Installing a driver that you obtain directly from a device manufacturer also automatically registers the device driver in Windows.

When a hardware device is then connected to the Calman for the first time, the proper device driver is automatically associated with the device.

Unsigned Device Drivers

Many currently available device drivers have not been tested and certified by Microsoft. These drivers are referred to as unsigned device drivers. Some of the drivers provided in the SpectraCal Device Driver Pack are unsigned.

Windows 7 or Earlier

If you are installing an unsigned device driver in Windows 7 or earlier, a Windows Security dialog will open to give us a choice of whether or not to install an unsigned device driver. If you feel comfortable with the source of your device driver file, you will probably want to select the Install Anyway option.

Windows 8.0 or Later

If you are installing an unsigned device driver in Windows 8.0 or later, you will need to follow one of the special driver installation procedures below.

Windows 8.0

Open Settings (move your mouse to the top or bottom right corner of the screen and wait for the charm bar to appear, then click the Gear icon)
Click Change PC Settings
Click General
Scroll down and click Restart Now under Advanced Startup
Click Troubleshoot
Click Advanced Options
Click Windows Startup Settings
Click Restart
When the computer restarts, select Disable Driver Signature Enforcement from the list.
You can now load the unsigned driver(s). After restarting the computer, any drivers that you installed will continue to function.

Dell Device Drivers Update

Note: This may need to be repeated each time you update your graphics driver.

Windows 8.1 and Windows 10

While holding down the Shift key, go to SettingsPowerRestart
On shutdown, you will be presented a list of Options. Select Troubleshoot
On the Troubleshoot menu, select Advanced Options
On Advanced Options, select Startup Settings
Click Restart - Machine will reboot.
This will bring you to Startup Settings. Select 7 - Disable driver signature enforcement

When Windows starts, Driver Signature Enforcement is disabled.

You can now load the unsigned driver(s).

After a normal reboot, Driver Signature Enforcement will re-enable. Any drivers that were installed while it was disabled will continue to function.

Windows Device Manager

When a USB-controlled hardware device is connected to a computer, Windows first needs to recognize the device and properly connect to it. The proper device driver needs to be registered with Windows to support that device connection. Only if Windows is properly connected to a device, will Calman also then be able to connect to the device.

Windows Device Manager is the important software utility for managing Windows connections to the external hardware devices that we are then going to want to connect to Calman. Device Manager allows us to check a device connected to Windows and manage the device’s driver registration.

Note: When Calman is unable to connect to a USB-controlled hardware device (or a USB to serial converter), Device Manager is one of the first places to check.

Any device that is connected to a computer’s USB port will create a device listing in Device Manager. The device will either be listed under an existing device type (e.g. “Ports (COM & LPT)”, or a new Device Type will appear (e.g. “X-Rite Devices”)

Under its particular Device Type, the device will be given a Device Description (e.g. “USB Serial Port (COM6),” “ColorMunki Smile”).

Alternately connecting and disconnecting the USB plug for the device in question may help to identify which device listing in Device Manager corresponds to the hardware device in question.

Virtual COM Port Drivers

Some USB devices use a Virtual COM port (VCP) driver, which causes the USB device to appear as an additional COM port available to the PC (listed in Windows Device Manager, under the Ports (COM & LPT) type, as a “USB Serial Port (COMx)” device.

Calman software can then access the USB device as it would a standard COM port. Note the designated COM port number in Device Manager (COMx), as you will need to select that port number on the Calman device connect dialog.

Normal Device Manager Listings

Following are many of the popular hardware devices that are supported by Calman that require a Windows device driver to support their USB connection. Following each device name is the Device Type and Device Description, as they will be listed in Device Manager when the proper device driver is installed.

If your device is listed some other way in Device Manager, the device driver is not installed properly.

Updating a Device Driver

If a hardware device was connected to the computer before its correct device driver was installed, Windows may have registered an incorrect device driver to the device. In that case, you may need to uninstall the incorrect driver (in Windows Device Manager), then reconnect the device to the correct device driver.

Follow these steps to update a device driver:
