please go to device managerand check whether all the usb ports are working properly then if any one is having a problem try updating the driver.if there is no problem with your usb port then there is a problem with usb device driver.install those drivers it will solve the problem
Firstly, you should check up when you attach a device to your computer, if there is an error message showing up at the right bottom of the desktop which says "USB Device Not Recognized". If so, you must haven't install the driver of the device properly or the driver is damaged.
Then you will need to download a new one from the website of the manufacturer and install it on your PC. Then the hardware will be recognized by Windows system and be able to work.
If there is no error message "USB Device Not Recognized" showing up, that means your USB driver is damaged or outdated. USB driver is used for detecting USB devices. Without it, Windows system will not be able to detect and recognize any USB hardware. The only way to solve the problem is to install a new USB 2.0 driver for your computer.
No matter which issue it is, the problem always result from outdated or damaged device drivers. To solve and avoid hardware not working problems is to update the drivers regularly. Because all drivers have bugs more or less and lead to a lot of unexpected computer errors. Chipset manufacturers, like NVIDIA, ATI, Intel and so on, update and release new drivers for their products.
So you just need to download and install new ones for your computer.
yes. you must first register the device with your computer through the bluetooth manager. once they are linked you can transfer the install cab file by blutooth, but you must actually install the file from your device. please rate me if this helps. thanks and good luck!
Got the easiest solution to the problem. It worked for me, hope it helps all of you too.
First of all, if the device is unrecognizable, go to Device Manager and remove (not disable) the device. After doing so, remove the USB connector from the port.
Next, go to http://www.logitech.com/en-my/support-downloads?wt.mc_id=usym_redirect_/index/downloads, and look for your mouse/keyboard etc model. Choose the one that you own and choose the Software Downloads option. Next, follow the steps and install the Logitech Connection Utility.
Once installed, follow the steps given and hopefully your device should be reconnected once again. Hope it helps all the best!
uninstall driver then turn off the PC then unplug the power cord from power socket, short its legs then leave it unconnected for 5min, then reconnect it to power socket and turn on PC and install driver it should work :)
