Hi. I will just enumerate some errors that i had trying to compile it with mingw:

I am using Codeblocks IDE which comes with mingw.

--- cannot find -lusb
libusb.a doesnt exists (at least not in my instalation) but seams like the problem is solved by removing -lusb

--- bzero is not defined (which should be in string.h)
From here : http://www.opengroup.org/onlinepubs/000 ... bzero.html
The solution is to define this macro.
#define bzero(b,len) (memset((b), '\0', (len)), (void) 0)

Hope it helps someone.

After having compiled command-line tool in windows, it doesnt works.

It just doesnt find the device and i dont know where else to try:

checking HID path "\\?\hid#vid_16c0&pid_05df#6&357e0f0f&0&0000#4d1e55b2-f16f-11
cf-88cb-001111000030}"
opening failed: 5
error finding DataStore: The specified device was not found


But i tryed with libusb-win32 and it does works.

This requires to only install the file libusb-win32-filter-.....exe

And i edited the file hiddata.c replacing

#if defined(WIN32)

with this:

#define LIBUSB
#if !defined(LIBUSB) && defined(WIN32)

This will let me choose if i want or not compile with libusb or the windows API.


Just to learn more, i would like to know what can the problem be with the windows API.
I am using WinXP with the free DDK provided by mingw.

Are you sure your hardware is working?

I tried hidtool on Linux first. It worked after some general debugging, like moving the physical connector between USB-ports.

After reading your first post I could compile it on Windows. hidtool.exe worked with my hardware right away.

Yes it works great with libusb under both OSes.

Im glad that it worked for you, then it is not a code problem. It could be that i have windows xp inside a virtual machine, but all other usb devices and libusb-win32 on the same OS works fine.

Anyway, using libusb was much easier than the instructions listed on his webpage. I have only installed the filter driver and compiled with libusb (commented the windows api part) and it worked perfectly.

Also i dont know if everybody thinks equal, but i find the windows api a total mess. I try to aboid it as much as i can.

Regarding bzero: Seems to be a problem of header versions. My MinGW installation has it...

Regarding -lusb: You need to install libusb-win32. This is a separate install not included with MinGW. The example demonstrates how to use direct (libusb based) access to HID devices.
