急！如何得到usb设备的句柄（handle）？

我的usb硬件设备信息如下：
Signature="$CHICAGO$"
Class=USB
ClassGUID={36fc9e60-c465-11cf-8056-444553540000}
provider=%Anchor%
DriverVer= 05/17/2002,3.0.0.0

%EzUsb_Desc%=EZUSB_Inst, USBVID_0547&PID_1002
%EzLoader_Desc%=EZLOADER_Inst, USBVID_0547&PID_2131

Anchor="AnchorChips"
EzUsb_Desc="Anchor Chips EZ-USB Generic Device"
EzLoader_Desc="Anchor Chips EZ-USB Loader(2131Q/2131S/2135S) - EEPROM missing"

能否能给出VC或Delphi的代码示例？
各位大侠帮帮忙啊！
