USB device not recognized. The last USB device connected to this computer malfunctioned.

System Restore used to be your first line of defense until Microsoft disabled it by default in Windows 10. So as long as you knew you had to turn it back on...

Hi Aayoush. I'm Greg, 10 years awarded Windows MVP, here to help you.

2. See if you can System Restore to a point before the problem started:

System Restore is your first line of defense and can take you back to a point before a problem began like a time machine. If it doesn't help then you can undo it. Read about it first in the tutorial above and then try restoring to just before this started. If System Restore is not enabled on C drive do that now so it's available in the future.

If the problem repeats or System Restore doesn't work then check which Windows Updates were installed at Settings > Update & Security > Windows Updates > Update History, uninstall them there or System Restore again, then immediately check for and block the Updates with the Hide Updates tool explained here: https://www.droidwin.com/how-to-stop-only-a-spe...

3. Update your Chipset and USB drivers from the PC maker's Support Downloads web page for your full model number, HP Serial Number, or Dell Service tag from the sticker on PC.

While there check that you also have the latest chipset, BIOS, display, network, bluetooth, USB and all other drivers, compared to the ones presently installed in Device Manager reached by right clicking the Start button.

Compare the latest drivers with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

If no newer or this doesn't help, then go to the USB category in Device Manager, open each Enhanced, Hub and Host controller, from Driver tab select Roll back if available, or if not choose Uninstall.

If your keyboard and mouse are USB, first program the power button to effect the needed restart after Rolling back or uninstalling the driver. Go to Settings > System > Power & Sleep > Additional Power Settings > Choose what Power buttons do to choose Shutdown.

Finally open the USB controller drivers, from Driver tab choose Update Driver, then Automatically. If that doesn't help then choose Update Driver > Browse > Let Me Pick to try all previously installed drivers queued there.

4. Establish a Clean Boot to turn off Startup Freeloaders that can conflict and cause issues:

5. Download, install and run a full scan with free Malwarebyes from https://www.malwarebytes.com/mwb-download/ after enabling Root Kit scan in Scan Settings. Clean Up anything it finds and then run again. Turn off Real Time trial in Control panel to keep as on-demand scanner.
6. Run System File Checker/DISM in WIndows 11 to find and fix any broken System files:

7. If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems: https://www.elevenforum.com/t/repair-install-wi...

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
