good. At least this gives a clear indication of what's failing inside
the windows_init() function of libusb; the relevant snippet of code
corresponding to the LIBUSB_ERROR_NOT_SUPPORTED code (which in turns
corresponds to the error description you got) is:

		// Detect OS version
		memset(&os_version, 0, sizeof(OSVERSIONINFO));
		os_version.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
		windows_version = WINDOWS_UNSUPPORTED;
		if ((GetVersionEx(&os_version) != 0) && (os_version.dwPlatformId ==
VER_PLATFORM_WIN32_NT)) {
			if ((os_version.dwMajorVersion == 5) && (os_version.dwMinorVersion == 1)) {
				windows_version = WINDOWS_XP;
			} else if (os_version.dwMajorVersion >= 6) {
				windows_version = WINDOWS_VISTA_AND_LATER;
			}
		}
		if (windows_version == WINDOWS_UNSUPPORTED) {
			usbi_err(ctx, "This version of Windows is NOT supported");
			r = LIBUSB_ERROR_NOT_SUPPORTED;
			goto init_exit;
		}

this means that your system seems not supported by WinUSB (or
incorrectly detected maybe).
If you open an MSDOS prompt and type "ver", what do you get?
Are you sure that your virtual machine is WinXP and not Win2000 ?

ok but this doesn't help now since we have completely moved away from
libusb-win32 0.1 and the  libusb-1.0 (which is what we're using now)
windows support was written from scratch and uses a completely
different approach from libusb-win32 0.1.

strange. Btw I'm using Vmware Player (which is free) and under that
system UsbPicProg works fine in a virtual WinXP SP3 and is also able
to connect to the hardware since Vmware can forward the USB traffic to
the virtual machine.

ok, many thanks!

good point. An entry is missing. I'll look into fixing this.

ok, so you can confirm that it works under a Win7 x32 ? ;)

Thanks,
