When you use USB devices in Windows, Windows will load and install a device driver to communicate with the new USB device. A lot of standard USB device drivers are included with Windows XP, even more in Vista, Windows 7 and 8. But if the USB device is not supported by Windows, you will see a USB device not recognized error like the one below.
You can try unplugging the USB device, waiting a few seconds and plugging it back, but chances are the error will remain.
Another error message that is common is the message Unrecognized device has been found.
When you open the Windows Device Manager from the Control Panel, you will generally see the USB device under the Other devices or Unknown devices category.
In case of an external hard disk, you may also get the error:
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.
Also keep in mind that if you don’t have the right USB drivers for your device, Windows might be using a default, compatible driver, which restricts the performance or limits the features of your USB device. This is particularly true for USB 2.0 and USB 3.0 ports.
How to fix a USB device not recognized error.
Considering the fact that in most cases the USB device driver is missing in Windows, the common solution to fixing the USB device not recognized error is to install the driver for the USB device. In most cases new USB devices come with a driver CD which contains the USB driver that needs to be installed. If you do not have a driver CD, you can try to find and download the USB device driver on the manufacturer’s website.
In case you really can not find the device driver for the USB device, you can use a driver finder program. Such a program will find and download device drivers on your PC based on the hardware that it automatically identifies. Even if your USB device is not plugged anymore, the application will be able to find and download a USB driver for it.
When you do have a driver CD, it’s still smart to use a driver update program to get an updated driver for your USB device. Drivers on CDs are quite often outdated and updated drivers can solve problems, improve performance and add features.
A second benefit to a driver finder program is that it can update all outdated drivers on your system. This means that the system or chipset drivers will also be updated, including the USB chipset drivers on your motherboard. This could also solve the USB device not recognized error, whether it is a USB 2.0 port or USB 3.0 port.
Other methods to repair the USB device not recognized error
In case the USB driver update does not solve the USB device not recognized error, there are a few other things that you can try to solve the error.
- If your USB device is using a separate USB cable, try changing the cable to make sure the USB cable is not defective. For external hard disks that are not recognized, a shorter USB cable can sometimes help as the power voltage can be a problem in those cases.
- If you are getting a USB not recognized error when you are trying to connect a mobile phone or MP3 player, check the configuration options on the device itself. The settings often allow the device to be configured as a Mass Storage Device, which can solve the problem.
- Check the BIOS of your computer to make sure the USB ports are configured properly. Most new USB devices work best with the USB 2.0 configuration, but in some cases you might need to change the USB to “legacy” support, which means version 1.1.
- Disable the power management of USB hubs on your computer. This can sometimes help with certain USB devices, especially if the problem happens with power state changes (resume from hibernation for example).
- In the Device Manager, right-click the Universal Serial Bus controllers device and select Uninstall in the popup menu. Now reboot and Windows will reinstall the device.
- In case you are using a USB hub, try plugging the USB device directly into the computer instead of in the USB hub. USB hubs often cause compatibility problems with certain USB devices. The cause can be the USB version compatibility or a USB power limitation.
- Try shutting down the computer altogether and unplug it from the power supply. Wait for a few minutes before plugging it back again and starting it. In case you are using a laptop, also unplug the laptop battery in this step.
- Delete the related registry key under “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB” from the Windows registry. Each USB device has an entry there starting with “VID_”. Find the related entry to your USB device and then delete it. Make sure you make a backup of the registry before deleting anything!
Restart Windows and then try plugging the USB device again.
- Specifically for Windows XP, there is another possible solution that is related to the Windows Registry. This pertains to removing the UpperFilters and LowerFilters registry values. Microsoft has a knowledge base article on how to do this.
Further useful programs to deal with USB problems are USBDeview, which is a freeware utility to view USB devices, and USB View from Microsoft. They show a lot more about your USB devices than the Device Manager does, so they can be helpful to pinpoint problematic USB devices. The USB View program from Microsoft has the advantage that it shows the hierarchy, so you can see which device is connected to which USB Controller and USB Hub. But the program is part of the Microsoft development tools, so unless you can find a reliable individual download, you need to install complete development environment.
Most USB device not recognized errors can be solved with one of the above solutions. If you have any other solutions, or a USB problem that did not get solved using these tips, please leave a comment and I’ll get right on it!
When you are running Windows 8 or 8.1 on an older system, or laptop and it is using an Intel graphics chipset, you might run into an issue with a low screen resolution error. The Metro interface requires a display resolution of 1024 x 768, but that is not always supported by the available display driver on this type of systems.
Typically you can get this on systems with a Intel GMA 3150 or even an Intel 945 series chipset. The driver will only support the 1024 x 600, which will result in an error message stating “This app cannot open” and/or “The screen resolution is too low for this app to run”.
There is a work around available that can work for this problem. It means installing the latest Intel driver for the graphics chipset (pick the latest Windows 7 driver if Windows 8 is not mentioned). Once installed, reboot to make sure everything is working.
After that you need to edit the registry to force the resolution to be changed. So first make a backup of the registry so you can revert back to that in case of problems!
After making the backup, open the registry editor (search for “regedit”), and press Ctrl+F to initiate a search of the registry. You need to search for the term “Display1_DownScalingSupported” and change the value from 0 to 1. After that, close the registry editor and reboot the computer.
The last step is to actually change the screen resolution from the Control Panel and set it to 1078 x 768. After that the apps using the Metro interface should work fine.
In case of problems, just reboot and press F8. Then select the Advanced Repair Options to start Windows in Safe Mode and restore the registry to the original settings. Then reboot and the screen should be fine again (although without the support for the 1078 x 768 resolution).
People with Windows based computers sooner or later start wishing that their computer was as fast as when they bought it. With use Windows tends to get a bit slower every day.
Most of this is the result of installing and uninstalling software, which leads to hard disk fragmentation and the registry growing. Fact is that not all software has a clean uninstall, so remnants will remain both on disk and in the Windows registry. In addition, more and more software try to install startup components, which will slow up the PC startup time.
Running a disk cleanup on a regular basis will help, and if you also schedule a disk defrag, you will already benefit from better PC speed. Taking it a step further to reduce the number of startup programs, and cleaning the Windows registry, will also optimize PC performance.
FreePCCleaner is a software program that can be used on Windows XP, Vista, 7 and 8 based computers to optimize the performance by cleaning and defragmenting the registry. There is also a feature to manage the startup programs.
Using the program is very simple. After installation, you click the scan button and wait for the registry to be analyzed. Depending on the size of the registry and the computer speed, the scan can take a minute. But once the result is available, the software automatically creates a backup of the registry, and you can repair the errors found, which includes all cleanup.
The Manage Startup feature allows you to see which programs all run at startup, which is more than only those in the All Progams -> Startup folder. A simple checkbox enables you to disable any program that you do not want to start automatically.
Another useful feature is found in the Settings, and is a scheduler, that enables you to automatically run the program at predefined intervals. This way you don’t forget to manually run FreePCCleaner.
Although Windows Media Player has improved over the years, the best solution for media playback on Windows is still VLC in our opinion. The support for almost all audio and video formats is a great benefit, but it is also simple and straightforward to use.
But if you are using VLC on a slower computer, maybe a Windows XP based system for example, you might face some performance problems with video playback. Especially large resolution videos requiring lots of processing can cause delays or rendering problems.
It is however possible to tweak the VLC player a bit to ensure it will get all possible CPU resources when playing a video file. The general problem with multitasking operation system (like Windows), is that the CPU is shared amongst tasks, so a single process will never get all the CPU time.
VLC has a setting that allows the user to increase the priority and as a result get more CPU time. This can help in playing the movie that just won’t play properly on your computer!
To change the VLC setting for increased performance, open the player, and in the Tools menu, select Preferences (or press Ctrl+P). This will bring up the Simple Preferences window.
In the bottom left of the window, you need to select the All option for the Show settings feature.
This will change the thumbnail view on the left to a list view with more options.
In the list, you need to select the Advanced option, and check the option named Increase the priority of the process.
Although you can experiment with the Clock source option, generally the Auto setting will already do the trick.
Click Save to store the settings and then play your media file again!.
Note: Be prepared that the responsiveness of Windows and other applications will be a lot slower (although you should not run those in the first place when dealing with performance issues).
My PC crashed the other day. I know, BUMMER! After re-installing everything, I noticed that in Outlook 2010, I was not seeing the REPLY mark or icon that marks emails I’ve replied to. You know, that little purple arrow pointing to the left that tells me that I’ve already addressed a particular message.
If you receive a lot of emails like me on a daily basis, then you know how that that little arrow helps save you a lot of time because then you don’t need to second guess yourself if something has been addressed or not!
Anyway, on to our solution!
How to Mark Emails as ‘Replied’ in Outlook 2010
- Open Outlook 2010.
- Click the View tab.
- In the Arrangement group, click Add Columns.
- Under Available Columns, click Icon and then click Add.
- Click the Move Up or Move Down buttons to position the Icon where you want it.
- Click OK.
We all know that using battery powered equipment has the disadvantage of the device running out of power. In the case of laptops running Windows, you can use the power management options to optimize the use of the battery by allowing the hard disk to be powered down and running the CPU at lower speeds.
But of course there are more options to maximize the use of your laptop’s battery. The more programs are running, the more the CPU is active. So disabling Windows features and services can further help to optimize the use of the battery.
A useful program for this is called BatteryCare, which is free and can be downloaded from the BatteryCare.net website. It goes much further than the Windows power management options. You can see in the options that there are quite a few additional features to save energy.
Most will cause no problems, but the option to disable the Windows services is something that needs to be tested, as it could conflict with specific software that you might be using.
If you use the option to let BatteryCare control the power plans defined in Windows, you can disable the Windows battery icon in the notification area. Everything is accessible from the BatteryCare icon in that case anyway.
BatteryCare also keeps track of the recharging cycles and will recommend a calibration after a defined number of cycles. This will help the battery indicator to be as accurate as possible, preventing you to be surprised by a low battery situation. Of course there are warning and notifications that can be configured, but if the basis for those notifications is incorrect information, the notifications come too late.
For more information on battery optimization make sure to also look at our previous article on maximizing battery life.
