The call to CreateFile may fail on some Windows 2000 systems. The
solution is to use a SECURITY_ATTRIBUTES parameter in CreateFile. Make the 
following three changes:

Change:

DeviceHandle=CreateFile 
  (detailData->DevicePath,
  GENERIC_READ|GENERIC_WRITE, 
  FILE_SHARE_READ|FILE_SHARE_WRITE, 
  NULL, 
  OPEN_EXISTING, 
  0, 
  NULL);

to:

DeviceHandle=CreateFile 
  (detailData->DevicePath,
  GENERIC_READ|GENERIC_WRITE, 
  FILE_SHARE_READ|FILE_SHARE_WRITE, 
  (LPSECURITY_ATTRIBUTES)NULL, 
  OPEN_EXISTING, 
  0, 
  NULL);

Change:

Public Declare Function CreateFile _
    Lib "kernel32" _
    Alias "CreateFileA" _
    (ByVal lpFileName As String, _
    ByVal dwDesiredAccess As Long, _
    ByVal dwShareMode As Long, _
    ByVal lpSecurityAttributes As Long, _
    ByVal dwCreationDisposition As Long, _
    ByVal dwFlagsAndAttributes As Long, _
    ByVal hTemplateFile As Long) _
As Long

to:

Public Declare Function CreateFile _
    Lib "kernel32" _
    Alias "CreateFileA" _
    (ByVal lpFileName As String, _
    ByVal dwDesiredAccess As Long, _
    ByVal dwShareMode As Long, _
    ByVal lpSecurityAttributes As SECURITY_ATTRIBUTES, _
    ByVal dwCreationDisposition As Long, _
    ByVal dwFlagsAndAttributes As Long, _
    ByVal hTemplateFile As Long) _
As Long

Change:

Dim HidDevice As Long
HidDevice = CreateFile _
    (DevicePathName, _
    GENERIC_READ Or GENERIC_WRITE, _
    (FILE_SHARE_READ Or FILE_SHARE_WRITE), _
    0, _
    OPEN_EXISTING, _
    0, _
    0)

to:

Dim HidDevice As Long
HidDevice = CreateFile _
    (DevicePathName, _
    GENERIC_READ Or GENERIC_WRITE, _
    (FILE_SHARE_READ Or FILE_SHARE_WRITE), _
    Security, _
    OPEN_EXISTING, _
    0, _
    0)

In Figure 21-4, the top 1.5k resistor should be a pull-up to 3.3V (not a pull-
down). The resistor connects to D- and a pull-up enable switch.
