Are you using a wired, USB or wireless, Bluetooth mouse but find it disconnects and reconnects randomly? Then, you ask: why does my mouse keep disconnecting? How do I stop my mouse from disconnecting? Now, MiniTool will give you the answers in this post and you can easily fix the mouse disconnecting and reconnecting issue.

Click on ‘Device Manager’ and then double click on ‘Disk Drives’ to expand it. Look for your connected USB drive. Right-click on it and select ‘Uninstall drivers’. Click Uninstall when prompted to confirm the uninstallation. Now disconnect the USB thumb drive and then after few seconds, connect it again via USB port. The 4 x USB 3.1 Gen 1 ports on the back of the motherboard deriving from the CPU do NOT disconnect; they work fine. All other ports, according to the MSI X470 GPC manual, derive from the X470 chipset, and all of them disconnect - this includes front USB 3.1 Gen 1, internal USB 2.0, rear USB 2.0, and rear USB 3.1 Gen 2. My computer makes a noise when I plug something in the USB ports, and when I connect my phone, it connects, and a second later it disconnects. And it keeps going. It doesn't even charge my phone. I never had trouble while the phone was on, but now the battery drained out and I can't get it to charge anymore. If the issue is resolved, reconnect the other USB devices one at a time. Make sure your iOS device is still recognized by the computer after adding back each device. If one of these steps resolves the issue, but it comes back later, make sure you haven't changed how the device is connected. Go to Start → type sound settings and launch the Sound Settings app. Scroll down to Sound Control Panel and select this option. In the new Sound window, click on the Sounds tab. Select Device Disconnect and check when the sound is set to play. It should play when an external device is removed. You can also turn off the Device Disconnect sound.
