Syntaxfehler beim Kompilieren

[Fuba]

Hallo erstmal,
Habe da einen völlig nervigen Fehler vielleicht kann mir ja jemand helfen:

error C2143: Syntaxfehler : Fehlendes '{' vor 'PCH creation point'

Bei dem Ganzen Spaß soll nachher eine dll Datei zur Ansteuerung eines USB Gerätes heraus kommen. Als Hilfe benutze ich die libusb-win32 von sourceforge.net.

Dank& Gruß im Voraus
Philipp

Ausschnitt aus lib.c:

#include "usb.h"
#include <windows.h>
#include <stdio.h>
#include <string.h>
#include "lib.h"

usb_dev_handle *usbIODevice;// habe die Vermutung das der Fehler hier liegt!!

unsigned char writeBuffer[8];
unsigned char readBuffer[8];
EXPORT int searchDevice(int vendorID, int productID) {
struct usb_bus *busses;
struct usb_bus *bus;
struct usb_device *dev;

usbIODevice=NULL;

/* Find the device */
usb_init();
usb_find_busses();
usb_find_devices();
busses = usb_get_busses();

for (bus=busses; bus; bus=bus->next) {
for (dev=bus->devices; dev; dev=dev->next) {
if (dev->descriptor.idVendor == vendorID &&
dev->descriptor.idProduct == productID) {
usbIODevice=usb_open(dev);
return 1;
}
}
}
return 0;
}

t mir leid!
Habe das mit dem Source code wohl etwas zuuuuu gut gemeint!

Fakt ist das ich eine dll erzeugen will zu Ansteuerung Eines USB Gerätes!
Dazu verwende ich msvc6 und die Open Source Bib. Meine Vorkenntnisse was C++ an geht sind mittelmäßig... sagen wir mal so ich hasse Objekte!

Über Hilfe würde ich mich seht freuen!
Gruß
Philipp

und wo tritt der Fehler auf?
