usb port doesnt provide enough power for my mouse

Mia Cox |

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!

The premise of your question is unlikely. The voltage supplied over USB would not change and neither will the power requirements of your mouse. Most likely some circuitry inside is dying and it will need to be replaced.

There are a few things to check before calling the mouse dead:

  • First, try the mouse on another computer, a friend's laptop, Chromebook, anything that supports a USB mouse. If you do that and it does not work, it's the mouse which will save you plenty of time figuring out what changed on your system.

  • If the mouse is not dead, it could be the port. Try different ports on your computer. Preferably one that is connected right on the motherboard. If you are using a front-case-port, they could be defective or a cable got disconnected. If you are using a USB hub, remove it and try the mouse without it. In fact, as a sanity check, disconnect all other USB devices except for the keyboard. It is possible that there is interference or a new device attached is somehow lowering the voltage left for the mouse.

  • You did not say what operating system you are using but since you know the time-frame you should be able to get the update history and see what happened around that day. Any driver or kernel update could be suspicious. Most operating systems allow you to remove an update or restoring a previous version so that you can reboot and try the mouse again.

  • Before trying to remove updates, there is another way to check if the problem is related to the operating system. Some modern BIOS support mouse control, if yours does, try entering the BIOS (usually done by pressing DEL when booting) and see if your mouse responds. If it works, then you'll have to dig into the OS updates and newly installed drivers.

  • If your BIOS does not support mouse control, you can still try with a bootable disk (CD/DVD/USB), doesn't matter which. Just insert media (Linux Live Disks are free and very common) and see if your mouse works normally (even the Windows Installation Disk might have mouse control). You don't need to fo through the installation, just advance one or two screens until there's a cursor you can control.

The strategy for solving such issues is to eliminate what is not wrong. If you get the mouse to work in the BIOS or Live CD, then it has to be something running in your operating system. If it does not work without booting into the OS, then you have a hardware problem.
