Solution 3 – Update USB Composite Device Driver with tools
If you are unable to install a new driver with the device manager, you can do so using a drive manager program like Driver Easy. I recommend this program especially for users who are not too vast in the technicalities of computer usage. With Driver Easy, you can automatically update the driver. You also avoid installing an incorrect driver by mistake. Here is how to do it.
- Install the Driver Easy program
- Launch the program and click the 'Scan' button to scan your PC to detect driver issues.
- Click the Update All to download new updates automatically and to install correct versions of all missing drivers or those that are already outdated. Driver Easy will prompt you to upgrade to be able to do this.
