Uso desktop e não notebook.
HP p6540br.
Agora estou começando a entender melhor a questão.
Esse HP p6540br é um desktop e a webcam é externa, conectada numa porta usb, é isso?
Se for, já experimentou alternar entre as portas usb disponíveis?
Algumas webcam, por exemplo, não funcionam em portas usb 3.0 e eventualmente também não em 1.0, então, se o caso, é melhor certificar-se no setup tais e quais portas estejam configuradas como 2.0 de fato.
Exato! A webcan é externa da marca WebCam Bright 0046 e funcionava corretamente no Ruindwos 10.
Sim! Já alterei as portas das entradas USB e não há conflito! Todas liberadas no setup.
Segue os módulos de entrada USB
