You can't directly "add" a scanner to a USB. Scanners typically connect to your computer through USB ports.
Here's how you can use a scanner with your computer:
- Connect the scanner to your computer: Most scanners come with a USB cable. Plug one end of the cable into the scanner and the other end into a USB port on your computer.
- Install the scanner driver: Once connected, your computer may automatically detect the scanner and install the necessary driver software. If not, you can find the driver on the scanner's manufacturer website or on the CD that came with the scanner.
- Open the scanner software: Once the driver is installed, you can open the scanner software. This software allows you to scan documents, photos, or other items.
Example:
If you have a Canon CanoScan LiDE 220 scanner, you can find the driver on Canon's website.
Note: Some scanners may require additional software or settings to function properly with your computer. Refer to the scanner's manual for specific instructions.
