Bro try this.
Step 1- Right click My Computer.
Step 2- Click on Manage.
Step 3- On the left panel Click Device Manager.
Step 4- The middle panel click on Universal Serial Bus Controllers.
Step 5- Locate your USB.
For example,
Mine was Cruzer Blade.
Step 6- Click on it and check the device status.
For example,Mine was "There are no drivers installed"
Step 7- Once confirmed Click on the Driver tab.
Step 8- Uninstall the driver.
Nope I'm not trolling...it worked for me.

Hope this helped.
