I used mingw+minsys, when i trying to "./configure" it make an error - "checking for pkg-config... no checking for LIBUSB... configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config. Alternatively, you may set the environment variables LIBUSB_CFLAGS and LIBUSB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. To get pkg-config, see . See `config.log' for more details." On the following adress - http://www.freedesktop.org/software/pkgconfig there is nothing, can anybody help me?

I am going to use the DBUS messaging system to allow other applications to dynamically call the device and set the state and scanning modes. The reason I am pursuing this is because I have already modified the pam_bioapi source to include MySQL and OpenLDAP support but lack the funding for a Digital Persona U.are.U 4000 USB Biometric Sensor URU4S and have opted for something more cost efficient with the MS Fingerprint reader. Since the current pam_bioapi does not currently interface with the libdpfp I feel this is the way to go, however I have also thought that the additional support should be added to the bioapi framework vs. creating an independent daemon to access the libdpfp interface. Any ideas on this? I have begun creating a daemon for this utility which can run in the background and wait for interactions from the user.

Did someone find a workaround ? Thanks a lot. seb Tuhin Says: November 22nd, 2006 at 11:48 pm I overcame all the initial hurdles. Now I am having problem with the dpfp_get_irq() function. The looping hack does not work in windows. Second time it calls r = usb_interrupt_read(dev->handle, EP_INTR, (char*)buf, DPFP_IRQ_LENGTH,1000); after the first timedout, I get the “Windows has triggered a breakpoint in “mytest.exe� Any idea.

I didnt uploaded the code yet coz i'm trying to figuer out why capturing doesent work untill, you pass the "found new hardware" dialog installing the Digital persona software. once you installed you can uninstall the digital persona soft and still the driver works ok. I mean that at least for me winlibusb is not enough if you try to use the driver.And still dont know why. guido.pusiol@gmail.com Tuhin, i had no problems with the driver and i happily pass you the code as it is, i maked a dll.

But it seems to fail in dpfp_open() call. Do I need to install any driver. When I hookup the Microsoft Fingerprint reader in my PC, it brings the new Hardware Found dialog. Should I cancel it. Why dpfp_open() is failing? I installed libusb32.lib. I would appreciate any pointer. Thanks Hello,
