[libhid-discuss] Windows support?

[Adrian Parker]

Hello all,

I read in the libhid docs, "aims to support all operating system supported
by libusb: Linux, BSD, OS X, and Windows".

This seems to say that libusb supports Windows. But libusb doesn't seem to
support Windows (http://libusb.sourceforge.net/doc/intro-support.html).

I note that neither libusb or libhid includes the text "windows.h" anywhere
in their sources, so I suspect this is further indication that neither
libhid or libusb supports Windows?

libusb-win32 is a separate project than libusb.

So libhid will work with libusb-win32, just as it would with libusb?

I shall try that today. Thank you.

There's more than one libusb implementation; libhid also works on
Solaris, which has its own libusb, for example.
Linux, FreeBSD, NetBSD, OpenBSD, Darwin, MacOS X (and Windows through
the libusb-win32 project)."
The only OS specific code that I know of in libhid is the bit that
requests an existing driver to detach, and afaik all implementations use
the same libhid-based code right now which is portable.

Unfortunately not.

[Adrian Parker]

I'm confused. libhid supports Windows, the website says it do so by using
libusb. libusb's site seems to say it doesn't support Windows, but
libusb-win32 does.

And Xiaofan seems seems to say that libhid doesn't work with libusb-win32.

Can someone tell me how I would use libhid under Windows (what does it
depend on that WILL work under windows)?

libhid aims to support Windows. "aims to support" is quite a bit different
than "support".

Hacking and testing. ;-)

The next version of libusb-win32 (under development) *aims to support*
native HID back end. So libhid may benefit from it.

Wait a moment, I remember someone has ported libhid to Win32
in libusb-win32 mailing list. You may want to contact him (Rob Krakora).

Ok, I got the source code and I an build it with the free Visual C++.Net
Express 2005.

I do not have a good HID device to test this port. Anyway, just running
the first example here. It seems to work.

How did you manage to compile libhid?

I'm using Visual Studio 2005. I receive 240 Errors. I included a
config.h from Linux, but that doesn't make sense at all. See the
attached files.

I don't have a Windows machine to test this with, but you may get a
little bit more help from others on the list if you temporarily set
the system language to English, then post that build log. Please
compress the log as well (gzip or pkzip).

It looks like the ERROR() definition is conflicting with something in
wingdi.h:

c:\dokumente und einstellungen\simeon\eigene dateien\projects\libhid
\libhid\include\debug.h(21) : warning C4005: 'ERROR': Makro-
Neudefinition
c:\programme\microsoft visual studio 8\vc\platformsdk\include
\wingdi.h(98): Siehe vorherige Definition von 'ERROR'

I'm not sure which would take longer for me, installing Windows then
downloading all of Visual Studio Express and the platform SDK, or
learning enough German to decipher that log file :-)

[comicinker]

Peter, thanks for the translations.

Sorry for the German version, I thought with this amount of errors,
there must be a small problem in the very beginning and is easy to
solve.

I attached now the MSVC errors in almost complete English. I also
attached the config.h which I am using now, with some explanations
added.

As I said, I just added some header files to the paths, which I
arbitrarily copied from different systems and programs (see comments in
config.h), however, some need also the libraries for the OS, so it is
basically nonsense what I did. That's why I need some help, as I don't
know how to provide all the needed declarations and definitions.

Thanks in advance,

One other thing that will cause problems down the road is that
"bsd.c", "darwin.c" and "linux.c" all define "hid_os_force_claim()".

For now, I would suggest copying "bsd.c" or "darwin.c" to "win32.c",
assuming that libusb-win32 does not provide
"usb_detach_kernel_driver_np()". Then, include "win32.c" in the
project, and make sure that the other OS-specific files ("bsd.c",
"darwin.c" and "linux.c") are excluded.

Can you send the exact error message?

Note that depending on what error code you are seeing, it may be a
problem with the firmware (e.g. it does not support the transfer in
hid_get_input_report().)

[alfredo alvarez]

Here is the output from a run of my program it includes the error i also wanted to mention that the program ( firmaware) actually gets detected by my machine and runs with the normal windows driver fine. but when i try to use it to get a report i can't. If it is the firmware anywhere i can get a working example or someone i can talk to ?

So i'm again getting the broken pipe message this time is actually
the device for my project.

Can you send the exact error message?

Note that depending on what error code you are seeing, it may be a
problem with the firmware (e.g. it does not support the transfer in
hid_get_input_report().)
