/**

      USB device state. This enumeration represents all possible states
      of the USB device physically attached to the host computer regarding
      its state on the host computer and availability to guest computers
      (all currently running virtual machines).

      Once a supported USB device is attached to the host, global USB
      filters ({@link org.virtualbox_4_2.IHost#getUSBDeviceFilters()}) are activated. They can
      either ignore the device, or put it to USBDeviceState_Held state, or do
      nothing. Unless the device is ignored by global filters, filters of all
      currently running guests ({@link org.virtualbox_4_2.IUSBController#getDeviceFilters()}) are
      activated that can put it to USBDeviceState_Captured state.

      If the device was ignored by global filters, or didn't match
      any filters at all (including guest ones), it is handled by the host
      in a normal way. In this case, the device state is determined by
      the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
      or USBDeviceState_Available, depending on the current device usage.

      Besides auto-capturing based on filters, the device can be manually
      captured by guests ({@link org.virtualbox_4_2.IConsole#attachUSBDevice(String)}) if its
      state is USBDeviceState_Busy, USBDeviceState_Available or
      USBDeviceState_Held.

      
NOTE: 
        Due to differences in USB stack implementations in Linux and Win32,
        states USBDeviceState_Busy and USBDeviceState_Unavailable are applicable
        only to the Linux version of the product. This also means that ({@link org.virtualbox_4_2.IConsole#attachUSBDevice(String)}) can only succeed on Win32 if the
        device state is USBDeviceState_Held.
