USB build errors

[HyperEngineer]

I created a new project in VC2008. I added nothing to the code except these statements:

extern "C" {
#include <usb.h>
#include <usbiodef.h>
#include <usbioctl.h>
#include <usbprint.h>
#include <setupapi.h>
#include <devguid.h>
#include <wdmguid.h>
#include <InitGuid.h>
}

/*
  This define is required so that the GUID_DEVINTERFACE_USBPRINT variabl is
    declared and intialized as static locally, since windows does not
    include it in any of its libraries.
*/

#define SS_DEFINE_GUID(name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8) \
	static const GUID name = {l, w1, w2, {b1, b2, b3, b4, b5, b6, b7, b8}}
	
//	SS_DEFINE_GUID(GUID_DEVINTERFACE_USBPRINT, 0x4d36e979, 0xe325, 0x11ce, 0xbf,
// 		         0xc1, 0x08, 0x00, 0x2b, 0xe1, 0x03, 0x18);

	SS_DEFINE_GUID(GUID_DEVINTERFACE_USBPRINT, 0x28d78fad, 0x5a12, 0x11d1, 0xae,
		         0x5b, 0x00, 0x00, 0xf8, 0x03, 0xa8, 0xc2);

/*
Identifier GUID_DEVINTERFACE_USB_DEVICE 
Class GUID {A5DCBF10-6530-11D2-901F-00C04FB951ED} 
*/

//#define SS_DEFINE_GUID(name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8) \
//	static const GUID name = {l, w1, w2, {b1, b2, b3, b4, b5, b6, b7, b8}}
	
	SS_DEFINE_GUID(GUID_DEVINTERFACE_USBDEVICE, 0xa5dcbf10, 0x6530, 0x11d2, 0x90,
		         0x1f, 0x00, 0xc0, 0x4f, 0xb9, 0x51, 0xed);

When I build it I get these errors in the usb200.h file:

error C2332: 'struct':missing tag name
error C2011:'<unnamed-tag>':'enum' type redefinition
error C2059:syntax error:'constant'
error C2334: unexpectoed token(s) preceding '{'; skipping apparent function body

These all apply to line 91 of usb200.h. This is the code:

typedef union _USB_HIGH_SPEED_MAXPACKET {
    struct _MP {
        USHORT   MaxPacket:11;  /* 0..10 */
        USHORT   HSmux:2;        /* 11..12 */
        USHORT   Reserved:3;    /* 13..15 */
    };
    USHORT us;
  } USB_HIGH_SPEED_MAXPACKET, *PUSB_HIGH_SPEED_MAXPACKET;

Line 91 is: struct _MP {.

I have the same code in another project that works fine. I don't remember if I had to do anything else to make it work.

Thanks,

If it ain't broke, it probably needs improvement.

It needs a tag name (like mp)

typedef union _USB_HIGH_SPEED_MAXPACKET {
    struct _MP {
        USHORT   MaxPacket:11;  /* 0..10 */
        USHORT   HSmux:2;        /* 11..12 */
        USHORT   Reserved:3;    /* 13..15 */
    } [COLOR=red][b]mp[/b][/color];
    USHORT us;
  } USB_HIGH_SPEED_MAXPACKET, *PUSB_HIGH_SPEED_MAXPACKET;

Thanks xwb,

Sorry about not getting back earlier. Been real busy around here.

The USB200.h is not my file. I believe it's a Microsoft file. But I did find out what I did before. I had to add this line to the stdafx.h file:

#undef _MP

I don't remember where I got that answer. And I haven't had the time to see where _MP was #defined in the first place, and what it is used for other than the USB function.
