usb webcam isn't detected

Hi People,

I unplugged and plugged my webcam, but isn't detected

  lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

lsmod | grep usb
usbcore               183764  3 ohci_hcd,ehci_hcd

What's is wrong? I can't figure out why kernel don't detect.

Re: usb webcam isn't detected

Have you tried a different USB port? Is it detected on other computers?
