• Required packages for compilation: gcc, automake, autoconf, make, patch, libtool, vim, ed, libusb-win32, libusb1.0, libusb1.0-devel, wget
• To install the required Cygwin packages from command line, execute the following commands. Have wget installed before. If you get an error “md5sum: standard input: no properly formatted MD5 checksum lines found” when executing apt-cyg have a look at http://superuser.com/questions/894696/apt-cyg-install-return-md5sum-error

wget https://raw.githubusercontent.com/transcode-open/apt-cyg/master/apt-cyg
chmod +x apt-cyg
mv apt-cyg /usr/local/bin/
apt-cyg install gcc-core automake autoconf make patch libtool vim ed libusb-win32 libusb1.0 libusb1.0-devel \
  procps dialog curl

• Required packages for running iButton Manager: procps, dialog, libusb-win32, libusb1.0, curl
• Download owfs from http://owfs.sourceforge.net
  • Extract the source code
  • Compile owfs by issuing

./bootstrap
autoreconf -if
./configure --disable-owtcl 
make
make install

Download libusb-win32-devel-filter and install it. Start the INF-Wizard program, choose the device (Vendor ID 0x04FA, Product ID 0x2490) and generate a corresponding INF file. Update the driver for the DS9490-USB-Adapter in Windows-Device-Manager and indicate the directory containing the generated INF-file. If necessary remove any previously installed Dallas driver http://owfs.org/index.php?page=windows-usb.

Afterwards testlibusb should report the USB-Adapter

$ testlibusb
  Dev #0: 0000 - 0000
  Dev #1: 04FA - 2490

Connect the OW-USB-Adapter and start owserver, owhttp. Then browse to http://localhost:3001/

/opt/owfs/bin/owserver.exe -u -p 3000
/opt/owfs/bin/owhttpd.exe -s 3000 -p 3001

#Read directory 
/opt/owfs/bin/owdir.exe -s 3000 /
