Hello,

I have a toshiba laptop and I recently developed a problem.

My computer always gives me an error in installing a hardware and need to reinstall and install again, and when I do that the same messege appears.

For example: if I plug my web cam, the microphone on the camera works but the camera doesn't! And when I plug in the printer (3 in 1) the printer works and the scanner doesn't, although I reinstalled it and the same error in hardware installation appears.
And my digital camera is not recognized by my laptop now! And the web cam, printer and digital camera were all working well before.
When I plug the mouse it works well.

Could the problem develop when I plugged in the webcam and digital cam at the same time?

(FYI: the plug is a USB port)

What could the problem be?
I need help please.
