mouseusb

The happened about 2-3 days ago. The problem is that my mouse suddenly stopped working and it said that the device not recognized or something like that. I just bought a new one but this one isn't working either. Whenever I plug the mouse in the laser lights up for a sec and starts to light poorly.

Did you attempt to go into Device Manager and remove all USB ports, devices, reboot and let Windows reinstall the drivers?

USB Devices Not Working Properly:

  1. Press Windows Key + R and type "devmgmt.msc" in the Run dialog box to open Device Manager

    Run dialog box

  2. When the Device Manager window opens, seek the USB device you're having problems with. It could be listed under Human Interface Devices as USB Input Device or if you don't see it there, expand "Universal Serial Bus controllers" to find the USB you're having an issue with.To find the one from the list for which you have an issue, you have to follow the trial and error method. That is, plug and remove the device and note the changes among the list of devices for Universal Serial Bus controllers. The entry which is appeared and then removed subsequently is the entry for issued device. Keep the device plugged in and right click over this entry, pick Properties.

    Device Manager

  3. In the device properties window shown below, switch to Details tab. Now click the drop-down menu for Property and select Device Instance Path. Note down the corresponding Value because we will need this value in further steps. By the way, this value is combination of three IDs; namely Vendor ID (VID), Product ID (PID), Instance ID.

  4. Press Windows Key + R combination, type put "regedit" in Run dialog box and hit Enter to open the "Registry Editor".

    properties

  5. Navigate here:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\<Device Instance Path>\Device Parameters

    Device Parameters

    Substitute the Device Instance Path part (after USB) obtained from the step 3.

  6. In the right pane of Device Parameters key look for the "DWORD" named EnhancedPowerManagementEnabled which must be showing its Value data as 1. Double click on the same to get this:

    DWORD

  7. In the above shown box, change the Value data to 0. Click OK. You may now close the Registry Editor as well as Device Manager.

Reboot the machine to get fixed!
