how do i know if my mouse is usb 1.1 or 2/0or 3.0
To determine whether your mouse is USB 1.1, 2.0, or 3.0, you can follow these steps:

1. **Check the Mouse Specifications**: 
   - Look at the packaging or the manufacturer's website for the mouse model. Specifications usually indicate the USB version.

2. **Physical Inspection of the Connector**:
   - USB 1.1 and 2.0 connectors are typically the same (Type-A), and both are usually white or black inside. However, USB 3.0 connectors are blue inside and have additional pins.
   - If your mouse has a blue connector, it is likely USB 3.0.

3. **Test on Different Ports**:
   - Plug the mouse into a USB 3.0 port (usually colored blue) and see if it works. If it does, it is compatible with USB 3.0, but it could still be USB 2.0.
   - If it only works in USB 2.0 or 1.1 ports, it may not support higher speeds.

4. **Check Device Manager (Windows)**:
   - Right-click on the Start menu and select "Device Manager."
   - Expand the "Universal Serial Bus controllers" section. You can see the connected devices and their specifications.
   - Look for your mouse in the list and check its properties to see if it indicates the USB version.

5. **Use USB Device Viewer (Windows)**:
  
To check which version of USB your mouse is compatible with, look at the back of the mouse for a USB port. If there is only one port, it is likely USB 1.1. If there are two or more ports, it is likely USB 2.0 or 3.0.
