ASP calling VB Dll

I have a VB DLL that I call from my ASP page.  The DLL is really just a shell around another Dll.  I just created my own functions that puts a little business logic in the DLL instead of doing it in the ASP page.

My problem is this:

I can call my dll from a quick vb app I wrote to test it and it works fine.  When I try to call it from Asp page I get some wierd results.

Here is the basis of my Dll that I am calling

Private Declare Function GetDevice _
   Lib "MYDLL.Dll" (byVal ID as Integer) as Long

Public Function C_GetDevice(ByVal GetId as Integer) as Long
    C_GetDevice = GetDevice(GetId)
End Function

From VB I do this:

Dim oDll as Object
Set oDll = CreateObject("CDUSB.MyDll")

rtn = oDll.C_GetDevice(0)

I receive 18481 back

From ASP I do this:
Dim oDLL
Set oDll = server.createobject("CDUSB.MyDll")

rtn = oDll.C_GetDevice(0)

I receive back -437385700
