How did you learn it? Why can't I learn it?

I tried using devcon to disable the camera, and it was disabled, but I can see in Device Manager that the camera device has a cross. After enabling the camera and restarting the computer, the camera can be used again. Is there a way to make others not see the camera in Device Manager?

After enabling the camera and restarting the computer, the camera can be used again? Of course it can be used if it is enabled. If it is disabled and still can be used, delete the camera's boot startup item. The location is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run To not see the X, you can disable the device manager in the policy.

Expert, the method you provided to disable the keyboard and mouse isn't working. I used devcon disable root\rdp_kbd* to try disabling the keyboard, but the returned result is: "Not all of one device(s) disabled, at least one requires reboot computer to complete the operation". Does this mean more than one device isn't disabled and at least one needs a computer reboot to complete? This doesn't work either. devcon disable pnp0303 returns the prompt: Acpi\pnp0303\4&31ad995d&0 : disable failed No devices disabled. Also, if I reboot, the keyboard can't input, then how do I enter the command devcon enable root\kdp_kbd* to enable the keyboard device? Directly use the mouse to enable it in hardware? But what if the mouse is also disabled? -------I'm a newbie. Hope the expert can answer, thanks! [ Last edited by nanhui112 on 2008-3-12 at 03:06 PM ]

devcon.exe disable USB\Class_03 This is to disable USB keyboards and mice. The mouse works, and you can enable it in Device Manager.

Then my keyboard and mouse can't be disabled, right? Then directly using devcon disable usb* to disable all USB ports is better?

Disabled things, try plugging it into another USB port and reinserting it?
