Hi,

I need to get raw USB packets with its protocol headers, these protocol
packets we need to convert to a pcap format to be decode by WireShark.

Is it possible with Libusb-win32 API to get these raw packets by
sniffing
the
USBus , or do we have to write a special kernel level filter for this.

Please be kind enough to guide us.

Thank you

Varuna

I am not an USB expert but I guess that the answer is no
and you need a special filter driver.

Do the existing open source sniffers like SnoopyPro and
SniffUSB work for you? Both of them use a filter driver.
1. SnoopyPro:
http://sourceforge.net/projects/usbsnoop/
2. SniffUSB
http://benoit.papillault.free.fr/usbsnoop/doc.php.en
http://www.pcausa.com/Utilities/UsbSnoop/default.htm

For libusb-win32, you can capature the debug message
and I think you are asking more than that.

Three steps to capature the debug message.
* add usb_set_debug(255) to your code after the call of usb_init()
* download DebugView from microsoft.com
http://www.microsoft.com/technet/sysinternals/utilities/debugview.mspx
* run DebugView to capture the driver's an the DLL's debug messages
Example output:

[Libusb-win32-devel] Question about removing driver files

[Vincent J. <vin...@gm...>]

Hello list,

Is there a way to manually remove libusb drivers files from the system (or
automaticaly using an libusb-win32 tool)?

I mean, during developpement, several .inf files can be created
(corresponding to different phase of developpement or different trials) and
installed, to test different firmware version of an usb device.
At the end of the developpement, there are several .inf files installed that
are out-of-date and useless, and (I guess several) instances in the system
registry.
Is there a way to find and remove all these files and references to these
usb devices that are no longer in use?
(For those of you who know the USBIO tool from Thesycon, the demo version is
delivered with a "cleaning wizard" that does what I am refering to here).

Can someone explain me how to proceed, or point me a ressource on the
internet.

Thank you
V.

Another question - is there a FAQ or something anywhere where people can

Re: [Libusb-win32-devel] Device Driver Installation problem

[#Cyrille37# <cyr...@gm...>]

Ok I've found the solution.

In the system properties, in the hardware manager, I'd a look at=20
"hardware identification numbers" and use exactly the same in the .inf :
    USB\Vid_03eb&Pid_ff07&Rev_0100&MI_03

=2EINF changes :

[Devices]
;;;"TUX RF DONGLE"=3DLIBUSB_DEV, USB\VID_03eb&PID_ff07
"TUX RF DONGLE"=3DLIBUSB_DEV, USB\VID_03eb&PID_ff07&Rev_0100&MI_03

[Devices.NT]
;;;"TUX RF DONGLE"=3DLIBUSB_DEV, USB\VID_03eb&PID_ff07
"TUX RF DONGLE"=3DLIBUSB_DEV, USB\VID_03eb&PID_ff07&Rev_0100&MI_03

and it's work !
In system hardware properties I've got :
    LibUSB-Win32 Devices

[Libusb-win32-devel] Device Driver Installation problem

[#Cyrille37# <cyr...@gm...>]

Hello,

I've just got a Tux Droid (tuxisalive.com) and all software are for 
Linux. That's normal ;-)
But I would like to develop software to run the Tux Droid on windows. 
The first step is to install an USB Driver for it.

I used inf-wizard.exe to generate the .inf File. At this point it's 
working. It generate a .inf file for USB Vendor ID: 03EB ProductID: FF07
The problem is when I plug the device and point the install wizard to 
the .inf file, windows tell that there is not device information in that 
file (the message is in french so I can't give the exact english version).

Perhaps it miss something, like a device familly for windows ? I really 
don't find any idea to make it work.

Thanks for help
cyrille.

[Libusb-win32-devel] Few questions about libusb-win32

[Kitsok <ko...@ki...>]

Hello all!

I'm developing custom gaming device and use libusb-win32 as a driver.
I use bulk read and write functions, and I'm stuck. 

I don't know if the problem is in driver or in firmware, but after some
consequentive bulk writes my host program fails with "write timeout". After
that I have to unplug my device, reset it and plug it back. Otherwise WinXP
even doesn't enumerate it. 

So I've decided to go deeper into the driver, and few questions raised:
1. Do I understand correctly that I have to use MinGW compiler to compile
the sources from SVN?
2. What branch should I take - libusb or libusb1?
3. And, finnaly, how to enable and read debug output of the driver?

Thanks!

Best regards,
Konstantin Klubnichkin

Hello,
 Thanks for the quick reply, I want to get these packets out from the USB
bus,
And I am happy about your remark that I can do it :-)

I used the USBSnoop and saw it decoding the URBs, But In order to use it I
believe
I have to modify it code (probably at the driver level) to capture the raw
packets to port them
to WireShark.

Instead Can I use the Libusb-win32 API, without modifying it, to get these
packets? Then I can work on the user level rather than at the Kernel level
to convert it to the format that,
WireShark can Understand.

Thanks

Best regards

Xavier

There are several hardware USB sniffers that can capture USB traffic,
but I never heard of one that can send it to wireshark.

It's also possible to sniff on the software level, capturing anything
(almost anything) exchanged between the USB driver and the USB device.
An example is http://www.pcausa.com/Utilities/UsbSnoop/default.htm

[Libusb-win32-devel] Possibility of Sniffing the USB Bus for the use in WireShark

[Varuna De S. <va...@gm...>]

Hi all,

Is it possible for us to sniff the USB bus, to get the raw USB protocol
packets, We need to get them and convert it to Pcap format to be decoded By
Wireshark.

If not the USB bus is it possible to sniff only to a particular device
attached to the USB bus. But we cant keep the device for ourselves
but only to sniff what is being transfered out from there.

If both these things are impossible are able to get the raw protocol
packets, with their protocol headers, from a device, to be decoded by our
software.

Thank alot

Best regards
Xavier

Sean:
        As far as my knowledge goes, libusb is for Linux platform whereas
libusb-win32 is for Windows platform. Their APIs are compatible with each
other.

Hi,



?



There appears to be two home pages for libUSB:



? http://libusb.sourceforge.net/index.html



? http://libusb-win32.sourceforge.net/



?



Are they describing the same product? Or are they describing
two different competing products?



Is there a difference between libusb and libusb-win32?



?



?



Faithfully,

[Stephan M. <Ste...@ia...>]

libusb.lib is *not* a static version of libusb0.dll it's just 
an import library that loads the DLL at runtime.

Apart from that I don't know (I'm no LGPL expert)
whether or not its legal to *statically* link a proprietary
application with a LGPL library.

[Libusb-win32-devel] usb_control_msg() returning -1

[Prabhu R <ece...@gm...>]

Hi Guys,

            I tried to use usb_control_msg() for a vendor specific request,
but its returning -1(failure). I have one of my device connected. My code is
given below.
My values for the parameter are the following,
RequestType - 0xc1 (vendor specific request)
Request        - 0x82
Value            - 0
Index             - 0
buffer             - char data[10]
length            - 10
timeout          - 1000

Please provide a suggestion.

Source Code:

#include <stdio.h>

#include "usb.h"

main()

{

int i;

char data[10];

struct usb_bus *bus;

struct usb_device *device;

struct usb_dev_handle *handle;

usb_init();

i = usb_find_busses();

printf("No of busses found = %d\n", i);

i = usb_find_devices();

printf("No of devices found = %d\n", i);

for(bus = usb_get_busses(); bus; bus = bus->next)

{

for(device = bus->devices; device; device = device->next)

{

printf("Starting to open device.....\n");

handle = usb_open(device);

i = usb_control_msg(handle, 0xc1, 0x82, 0, 0, data, 10, 1000);

printf("Return Value of usb_control_msg() = %d", i);

usb_close(handle);

}

}

getch();

}

Output:

No of busses found = 1

No of devices found = 1

Starting to open device.....

Return Value of usb_control_msg() = -1

Re: [Libusb-win32-devel] LibUsb_win32 license question

[Stephan M. <Ste...@ia...>]

To fulfill the requirements of the license (LGPL/GPL)
you ...

- DO NOT have to distribute the source code of your
  own application. The LGPL explicitly allows you to
  link your (closed source) application against the
  library
- if you distribute libusb-win32's driver or DLL
  along with your own application then you either
  have to provide libusb-win32's source code or
  point your users to a location where they can 
  download it. You also have to include libusb-win32's 
  licence and copyright so that your users know about
  their rights (and responsibilities)

[Libusb-win32-devel] LibUsb_win32 license question

[Vincent J. <vin...@gm...>]

Hello everybody on the list,

This is my first post on this list, and I hope that someone here could bring
me precisions, even if my question may sounds dumb.

I am developping an application for my employer (that is, a commercial
application, although this application will maybe be distributed freely).
This application uses LibUsb-win32 in order to establish an usb
communication with an usb device and exchange data via bulk transfers.
The application is (currently) compiled with VisualStudio, includes the
usb.h header and libusb.lib (in order to compile). The LibUsb-win32 library
in itself has not been changed in any way.

My question is about license and distribution : I have carrefully read the
LGPL v2.1, but I would like to make sure that I fully understand all the
terms, in order not to deny the authors rights in any way.

Since my application "contains no derivative of any portion of the library,
but is designed to work with the library by being compiled or linked with
it", it is a "work that uses the library", and I think that I am free to
distribute my application without providing the source code and/or the
object files of my application. Am I right?
In a case where my application would display copyright notice, I plan to
mention LibUsb-Win32.
I also plan to distribute the LibUsb-Win32 library, including copyright
notice, disclamer of warranty and a copy of the LGPL, as expected.

Could someone confirms that I not going the wrong way?
If I am not in a case that allows me to distribute my application without
providing the source and objets files of my application, what should I do to
be allowed to do so?

Thank you in advance for your support
And sorry for this rather boring question (My aim is to make sure that I
satisfy my obligations under the license, and to go against the rights of
the authors)

[Libusb-win32-devel] USB_BULK_READ() (amin mosayyebzadeh)

[Krakora, R. V <rob...@de...>]

It looks like there is possibly a bug in your code.  The variable i=
 contains the size of reading blocks and that is passed in to=
 usb_bulk_read().  However, if the size of reading blocks is greater than=
 the size of the allocated buffer then there can be a buffer overrun in the=
 driver causing a blue screen or PC reboot (based on how you have Windows=
 configured to handle the exception blue screen vs. automatic reboot).  To=
 fix this, malloc() the buffer after calculating the size of reading blocks=
 (do not forget to free it).  You can configure Windows to show a blue=
 screen instead of automatically rebooting.  The blue screen will indicate=
 in which driver the exception occurred and show a dump of registers and=
 memory.

I am not an USB expert but even with winusb.sys one still needs to
provide an INF file. Does that mean the situation will be any better
unless the INF is WHQLed? I do not have Vista now.

For example, people still need to provide an inf file for CDC-ACM
device even though they use the default usbser.sys in Windows.

The safe bet is HID which does not need an inf file in most cases.

I would like to help but I do not know much about programming. I
can certainly help for testing. I've tested the HID backend and
it is only partially working. Not so sure anout the WinUSB
backend since I am still learning how to use WinUSB. There
are very few WinUSB examples on the web. For example, I am
having problems with WinUSB here.
http://forum.microchip.com/tm.aspx?m=3D264046
Now I have an WinUSB host example in Visual C++ 2005
Express so I am learning how to use it.

Hopefully some other person will help Stephan to get the HID
and WinUSB backend to work. That would be really nice.

Xiaofan

hi all,
I use usb_bulk_read() for reading usb device sending data, but if I try to

if I plug device out then plug in to pc, I can read again. Do you know why?

[Libusb-win32-devel] USB_BULK_READ()

[amin m. <sir...@gm...>]

hi all,
I use usb_bulk_read() for reading usb device sending data, but if I try to
read once again, PC will be reseted.(in below code, when I change prime
value of k to 2).
if I plug device out then plug in to pc, I can read again. Do you know why?
thanks.

int usb_test(usb_dev_handle *udev, int cnt) {

    time_t start, end;
    double dif=0;

    ofstream ofile;
    ofile.open("result.txt");

    time (&start);
    time (&end);

   //PROBLEM IS HERE
    for(int k = 1; k>0; k--){

        char* rb;
        char* wb;
        int i=0, result;
        rb = new char[4096];
        wb = new char[2048];
        int count = cnt;

        //getting size of reading blocks;
        ifstream ifile;
        ifile.open("test.txt");
        while(!ifile.eof()){
           ifile.get();
            i++;
        }
        ifile.close();

        //reading received data
        result = usb_bulk_read (udev, 2, rb, i, 1000);
        if (result < 0) {
            printf("\nCould not read: %s", usb_strerror());
            return result;
        } else {
            count -= result;
            printf("\nread %d bytes ", result);
        }

        //print read buffer
        for (int j=0; j<result; j++) {
            ofile << rb[j];
        }
        time(&end);
        dif = difftime(end , start);
        delete rb;
        delete wb;
    }
    ofile.close();
    return 0;
}

I am not an USB expert but even with winusb.sys one still needs to
provide an INF file. Does that mean the situation will be any better
unless the INF is WHQLed? I do not have Vista now.

For example, people still need to provide an inf file for CDC-ACM
device even though they use the default usbser.sys in Windows.

The safe bet is HID which does not need an inf file in most cases.

I would like to help but I do not know much about programming. I
can certainly help for testing. I've tested the HID backend and
it is only partially working. Not so sure anout the WinUSB
backend since I am still learning how to use WinUSB. There
are very few WinUSB examples on the web. For example, I am
having problems with WinUSB here.
http://forum.microchip.com/tm.aspx?m=3D264046
Now I have an WinUSB host example in Visual C++ 2005
Express so I am learning how to use it.

Hopefully some other person will help Stephan to get the HID
and WinUSB backend to work. That would be really nice.

Yes. Search the forum and you will get some sample codes
from Stephan. I have used it on testing a simple isoc device
but I do not quite understand how it works right now.
