End Structure

User-Defined Field Types:

None.

Notes:

This structure is often nested inside the USB_HUB_INFORMATION structure, hence the need for the "pack=1"

typedef struct _USB_HUB_DESCRIPTOR {
   UCHAR  bDescriptorLength;
   UCHAR  bDescriptorType;
   UCHAR  bNumberOfPorts;
   USHORT  wHubCharacteristics;
   UCHAR  bPowerOnToPowerGood;
   UCHAR  bHubControlCurrent;
   UCHAR  bRemoveAndPowerMask[64];
} USB_HUB_DESCRIPTOR, *PUSB_HUB_DESCRIPTOR;
