PNP OS
set to Yes  The BIOS configures only critical devices (for example, video, hard-disk, and key- Board). NOTE: In this mode, neither the BIOS nor Windows configures the motherboard devices at startup. Therefore, for these earlier computers, you must set PNP OS to No.
PNP OS
set to No  The BIOS configures critical devices and all motherboard devices under the assumption that Windows cannot.  

Why were you directed to set PNP OS to Yes?
Does your bios have a PNP OS choice?

PnP should work automatically for your laptop. If your hardware doesnt show, it will either be a fault with the hardware or a fault with your laptop.

How old is the laptop, and what model and make is it ?

is there any other reason it could be damaged, for example, physical shock ? Do you have anti-virus software.

What operating system do you have ?

Its unlikly to have a PNP option - its just ON by default- no other option - it device that you are connection sounds like it uses USB 1, hence the warning.

what I mean is that the laptop assuming its a recent model is not going to have an option to switch PNP off - its got a PNP BIOS and its always ON, no option to switch it on/off.

The message you are seeing is that that tou sometimes get when attaching a device that does not support USB2 into a USB2 port. Assuming that the ports are USB2 - the device may only be USB1

the message saying 'this This USB device can perform faster if you connect it  to a Hi-Speed USB 2.0 port" is not an error but an advisory message.  If your laptop has more than 1 USB port then try plugging the device into another port.  Your computer may not have USB2.0 ports and only USB1.0 or 1.1 ports.

In your bios you MAY have the option to change the USB settings (Normal/High Speed/Full Speed) normal being 1.0, High 1.1, Full 2.0) set it to Full Speed if it gives you the option.

The webcam may be connected internally to a USB header, with it being intermittent, it probably has a loose connection which means you have to dissassemble the case to get at the connecter, which may or may not be a feasible option.  Lack of proper tools, experience and knowledge may make the addition of an external webcam a more viable option.
