The service is not part of the latest release any more. The latest version uses a different approach to install the filter. You can install the filter manually by using the 'install-filter.exe' command line tool. Type 'install-filter.exe -h' to see the available options. You can also include the install in your application (see install_filter.c for details).

Apart from that, I won't recommend to use the filter feature at all and use the device driver instead, because: * it's very likely that the filter won't work on Vista * the device driver will work on Vista * the filter doesn't work properly with some devices (this is a Windows issue) * the filter is a development tool, not intended to be used by "professional" applications * your users have to install a driver anyway, either the filter or the device driver, so they won't see any difference. > > Many thanks for your help and time! > > Georges > > > > ------------------------------------------------------------------------- > Take Surveys.

This reminds me: What is the state of libusb-win32 for Windows 2000? I found that the latest release does not even install with the DDK (3790.1830) in the Windows 2000 build environment. Does it mean that Windows 2000 is not supported anymore? What about Vista 64 bit? As far as I see, the driver is not signed, thus, it should refuse to install there. (I do not have Vista, so, I cannot check for myself). Do you plan to support 64 bit Windows at all? Regards, Spiro. -- Spiro R.

Windows 2000 is fully supported, even Win98SE. I just installed the 0.1.12.1 release (compiled with mingw) on win2k-sp4 (vmplayer install) and it works like a charm. Don't use the DDK's Win2k build environment, use the XP or the Server 2003 build environment even if you want to compile for Win2k. > > What about Vista 64 bit?

You are right, Vista-64bit won't let you install unsigned drivers. This means that this platform is currently not supported. To resolve this issue, future versions of libusb-win32 will use Vistas built-in kernel driver winusb.sys. > > Do you plan to support 64 bit Windows at all? XP-64bit and Server-2003-64bit are supported. Use the files libusb0_x64.dll and libusb0_x64.sys on these systems. > > Regards, > Spiro. > > -- > Spiro R.

I am sorry that I did not test it myself, but currently, I do not have a Win 2000 machine myself. I was very surprised because the Win 2000 build environment did not work. > Don't use the DDK's Win2k build environment, use the XP or the > Server 2003 build environment even if you want to compile for Win2k. I have had the opposite experience: Drivers compiled with the XP and 2003 environment did not work with the "lower" versions. > You are right, Vista-64bit won't let you install unsigned drivers. > This means that this platform is currently not supported. > To resolve this issue, future versions of libusb-win32 will use Vistas > built-in kernel driver winusb.sys. Ok, I wanted to propose the UMDF, but obviously, you are already aware of it. As I wrote you in my private mail, I am no specialist in USB. OTOH, I already wanted to start working with UMDF and KMDF myself. Thus, if you need any help in porting the driver, feel free to ask me. If time permits, I will try to help you, if you want. > > Do you plan to support 64 bit Windows at all? > > XP-64bit and Server-2003-64bit are supported.

Oh, you want to use winusb.sys directly? This sounds very interesting. Anyway, if I can help, just tell me. Regards, Spiro. -- Spiro R.

I won't mind help testing that (no matter how beta). I have some experience debugging USB stuff and I also have a microcontroller board available (LPC2148) that I can program as basically any kind of USB device for testing. (USB 2.0 full-speed only, isochronous currently not supported).
