CentOS doesn't see USB device

view story

http://unix.stackexchange.com – I'm running CentOS 6.3 inside of VirtualBox and am having trouble seeing my USB 2.0 thumb drive. In VirtualBox I go to Devices, USB drives and can capture my connected thumb drive. I've created a mount point in CentOS but fdisk doesn't show the drive (I'm expecting to see SDC) there. What am I missing? (HowTos)
