#define VRDP_USB_REAP_FLAG_LAST      (1)

#define VRDP_USB_CAPS_FLAG_POLL     (1)

Can some of vbox team members explain a bit on the above flags? In particular, what is the difference between  VRDP_USB_CAPS_FLAG_ASYNC and VRDP_USB_CAPS_FLAG_POLL? when VRDP_USB_CAPS_FLAG_POLL  is used, does it mean the vrdp server side invoke the URB reap method?
