If you want to read the report descriptor, it can be done fairly easily. 
See src/drivers/usb/generic/hidutils.c in the apcupsd package for an 
example.

[Stephan M. <ste...@we...>]

Sorry, but tutorials do not exist. Just google for 'libusb-win32' and have
a look at the source code of some projects that use the library.

The API reference is available here: http://libusb.sourceforge.net/doc/
There's also a .NET/C# wrapper: http://icsharpcode.net/OpenSource/SharpUSBLib/default.aspx

[Libusb-win32-devel] Please HELP!LibUSB

[SinaVIP <da...@vi...>]

Dear Sir,
 
 
   I wanna write a windows(win2k/winXP) program that grab video data from
USB Camera when the camera is used by another program, like MSN.  LibUSB
maybe is a good solution. I use it to access USB Camera in USB Filter mode
(not driver).
   It's all well to get the USB Bus/Device information, but when I call
usb_set_configuration, it does not work, return said "CRC Error", Please
tell me why?  Does it support isochronous transfer ? How i can the data from
USB Camera, any example ? 
 
 
Thanks
Danny

Re: [Libusb-win32-devel] Cancel_io

[Stephan M. <ste...@we...>]

I think this bug can be fixed by adding WaitForSingleObject() after _usb_cancel_io()

So, usb_cancel_async() would look like this:

int usb_cancel_async(void *context)
{
  ...
  _usb_cancel_io(c);
  WaitForSingleObject(c->ol.hEvent, 0);
  return 0;
}

Or, WaitForSingleObject() could be added to _usb_cancel_io() directly:

static int _usb_cancel_io(usb_context_t *context)
{
  int ret;
  ret = _usb_abort_ep(context->dev, context->req.endpoint.endpoint);
  WaitForSingleObject(context->ol.hEvent, 0);
  return ret;
}


Please let me know if this helps,
Stephan

[Libusb-win32-devel] Cancel_io

[Dan E. <Dan...@di...>]

We've seen some problems when stress testing doing plug/unplug.
Mysterious memory corruption was occuring and it turned out ot be in the
aynchronous context blocks.
=20
Part of the problem seems to be that the result of the _usb_cancel_io
function isn't used, so usb_cancel_async can return apparently
successfully before the io has completed. This can result in memory
corruption because Windows writes to the overlapped structure even
though the Event handle has been closed in usb_free_async.
=20
I'm not sure what the correct solution is, but it would help if
usb_cancel_async returned the error from usb_cancel_io so that we didn't
then try and free the transfer, but you'd then have to not call
usb_free_async if an error occured (or try it again until it succeeded).
=20
At the moment we've implemented a horrible solution of adding a delay
after the usb_cancel_io before trying to free it. By adding in checking
code, we can see that the memory gets altered sometimes even after the

Re: [Libusb-win32-devel] Multiple interfaces

[Stephan M. <ste...@we...>]

This check has been added for the filter driver functionality. It should p=
revent
the filter driver from attaching itself to the child device nodes that Win=
dows
creates for each interface, it should only attach itself to the parent dev=
ice node.
If this check wouldn't be present a device with multiple interfaces would =
show=20
up multiple times in libusb's DLL.

I'll try to change this in future releases.

BTW, is anyone actually using libusb's filter driver functionality for any=

[Libusb-win32-devel] Multiple interfaces

[Dan E. <Dan...@ne...>]

There has been mention in the past of support for multiple interfaces in
the releasee notes, and that it should work. However there is a line in
libusb_driver.c which explicitly prevents multiple interfaces from
working:
=20
  /* only attach the (filter) driver to USB devices, skip hubs */
  /* and interfaces of composite devices */
  if(!strstr(id, "usb\\") || strstr(id, "hub" || strstr(id, "&mi_"))
    {
      return STATUS_SUCCESS;
    }

However, commenting out the test for &mi seems to work fine and I can
use libusb on multiple interfaces.
=20
Is there a reason why multiple interfaces have been disabled in this
manner, as I'd like my device to present a standard class interface
(e.g. mouse) as well as my specialiased one?

[Libusb-win32-devel] Problem when install libusb

[Ha T. D. <duo...@gm...>]

Hi I am a new bee I apologize if the question is not appropriate
I just download 3 files from the project and run 
libusb-win32-filter-bin-0.1.10.1.exe
However, it come back to me a console screen and do nothing.
I am using WinXP SP2
Did i do something wrong here?  Do i have to do some more step before that?

Second question, I am trying to do make a control program for Microsoft 
Fingerprint Reader using Visual Studio 2005 C#. What sort of step that i 
need to do if i want to embed the project with my program? What kind of 
reference that i need to add into my project?

Thank you very much for your help.

I do appreciate  that.

Re: [Libusb-win32-devel] USB to LPT

[Stephan M. <ste...@we...>]

Basically it should be possible to control these LPT-USB adapters
with libusb(-win32). All you need is a datasheet of the chip that's
used by the adapter and a specification of its high level protocol.

The problem is that all of these devices use different kind of controller
chips which are most likely not compatible. Supporting all of them by=20
your application will be hard if not impossible.

If I where you I would design a custum USB-to-DIO converter. This
will save you (and your customers) a lot of pain.

Have a look at the FTDI web site (http://ftdichip.com/), especially=20
at their FT245 product. This might be what you need.

[Libusb-win32-devel] USB to LPT

[Mauricio H. <mhe...@te...>]

Hi to all:

My name is Mauricio and I new on the list, I write you from Chili.

I have a very basic question so be patience with me please.

I develop a domotic system for people with mobility problems 
(wheelchair, etc) (you can see more about the system in 
http://www.domosoft.cl in the "Galeria Multimedios" section). This 
system use some circuit conected to the PC in the LPT port, so to 
control the circuit my software use the "inpout32.dll" librarie, with 
this librarie I can write and read directly to the memory position of 
the LPT (data, status and control bytes)...and now this is my problem. 
Modern computer don't have LPT anymore and a quick way to conect my 
circuit is with a USB to LPT adapter, but with this kind of adapter the 
system have a "virtual lpt port", and I can't write directly in any 
memory position (this is correct right??). So, I want to build some kind 
of "driver/library" to write in some kind of "usb memory" or access to 
the "virtual LPT port" usb adapter and write the numbers for the LPT. If 
this posible with libusb-win32??, and also my adapter is recognized on 
linux and work with my printer, so is this posible for the linux version 
of libusb??

Thanks and sorry for the long explanation... :-)

You can use libusb in a C++ application without any problems. There's also=
 a C++ wrapper available.
See: http://svn.sourceforge.net/viewvc/libusb/trunk/libusb/ (files usbpp.*=
)

Just google for it. You'll find lots of examples. Most of the code is writ=
ten for Linux
but it will work on Windows as well.

That does rock, doesn't it? I had the same experience with Apcupsd where
I wrote a libusb-based driver for Solaris and Darwin and decided "just
for the hack of it" to try it on Windows...and it very nearly just
worked. A couple minor patches to libusb-win32 and it worked 100%.

We do this in the Apcupsd NSIS installer for Windows. Take a look at
winapcupsd.nsi
(<http://apcupsd.cvs.sourceforge.net/apcupsd/apcupsd/src/win32/winapcupsd.nsi?revision=1.12&view=markup>) for an example. Basically you install the 
*.inf, *.dll, and *.sys files and then run an entrypoint in the DLL to
actually register the driver.

[Libusb-win32-devel] control msg

[Sheng Xu <xus...@ya...>]

Hi, 

As I am doing a project of our lab, which require a PC
USB simulator that can send all types of control
message. But current libusb make all the control
messages as Vendor type, so could I request to add
features to make the control message be sent as user
want, especially the RequestType and Request.

Best Regards,

Xu Sheng

[Libusb-win32-devel] Install with another app

[Paul A. <pau...@gm...>]

I'm porting an application (OWFS http://www.owfs.org) that uses libusb under
Linux, FreeBSD and MacOSX successfully.

With a bit of fiddling, it runs under cygwin with libusb-win32. Quite a nice
testament to your work!

Now I'd like to package everything. I've gotten an opensource windows
installer (NSIS from Nullsoft) and have put in links to cygwin and
libusb-win32 to satisfy the GPL requirements. I'd like to make a binary
installation option that guide people though setup rather than send them to
multiple places to install multiple packages.

What do I need for the binary install? libusb0.dll? A .sys file? My .inf
file? Are there any configuration routines I should start?

Thanks,

Paul Alfille

[Libusb-win32-devel] Basic questions regarding the use of libusb-win32 and a bit more...

[Christian R. <chr...@gm...>]

Hi there.

I would like to borrow a few minutes of your precious time, to ask a few
questions regarding the development of a piece of software that is to
communicate with a "homemade" usb device. I'm relatively new to this kind of
programming so please bear with me - I'll appreciate it.

As mentioned, the software is meant to communicate very basically with a
piece of hardware - if the specific chipset type, id, etc. is needed I can
provide it, but it's some Texas Instrument thingy. The hardware records
various type of information when it runs, temperature, time and atmospheric
pressure which the program is meant to pick up and throw into a text file.
The communication between the program and hardware is supposed to be very
basic, something similar to the program sending a command to the device
telling it to start and stop - nothing more complicated than that.

Is this possible to achieve by using libusb-win32? I'm not that tough to
C/C++ that's why I'm a bit in doubt regarding if it's possible to use the
libusb in a C++ application since the only examples I've seen has been C
applications.

Also, I've been reading the documentation on the sites linked to at
libusb-win32's home, but I would like to know if there's somewhere there
exists some more, detailed examples of how to use libusb-win32 in order to
get inspired.

Thanks in advance
Christian Rasmussen, Denmark.

Thanks, I tried that, but it didn't quite work that way.

(Sorry, I didn't show that the above was followed by another
  control transfer that turns out to be related.)

It appears that the way SnoopyPro reports things, this is the first
part of two transaction that make up a single control message.
The control message was actually 0xC2 with wLength of 8,
(Hence "vendor" and "endpoint"), but the first thing reported
is the above, with a bmRequestType value of 0x00 and wLength of 0,
which is what confused me. Subsequently it reports a control transfer
with bmRequestType 0xC2 and wLength 8.

Doing a control message call with libusb results in the same reported
sequence, so it seems I can go ahead an emulate the windows driver
behaviour, which is what I was after :-)

I guess it's just reporting the way that USB works, something that
isn't that easy to figure out from the spec itself...

cheers,

Graeme Gill.
