Your friends are having difficulties with their computer setups. Can you suggest a way to help each friend? Jamal plugged his new touchpad device into the USB port. He keeps getting a message that says that the device is not recognized.
Felicia lost the driver CD for her new monitor. She can’t install the monitor without the correct driver.
Credence just recently changed from a Windows computer to a Mac. His Bluetooth headphones worked fine on the Windows computer but they won’t connect on the new computer.

The general answer for three problem is go to the company to download the latest driver, you can also download drivers via operating systems...

1) Update windows and check your drivers,

2) If monitor driver still missing then go the the companies website and download the monitors and usb driver from there.

If the USB port is part of the motherboard then you may download the USB port driver from that motherboard company...

Regarding the change from windows to Mac, check if OS support that Bluetooth product, in general one should be able to find the required drivers either by updating OS or contacting the drivers providers via their website...
