I Won't be able to put an online order due to some situations.

How would I make Windows 7 (32 bit) to recognize this incoming USB signal, and to send it to the MIDI applications in an appropriate format? Parts list (Veroboards, IC chips, capacitors, resistors, diodes etc) with part number to do this. Proper circuit diagram to connect MIDI to USB port. They does not show any option for MIDI devices. I have tried searching the In the control panel, the 'Device manager' and the 'Device and printers' options. The apps show a dropdown list that I have 2 MIDI output / synth interfaces ( 'Microsoft GS Wavetable Synth' and 'Microsoft MIDI Mapper'), but it shows 'BLANK' in the field for MIDI input Interface (even after I installed a few drivers from CASIO, ROLLAND, YAMAHA and a few random drivers from web, and restarted the machine for several times). The apps keep saying 'No MIDI input device found'. Some of the combination caused horrible buzzing in the built in speaker of the piano keyboard, and bleeping or flashing or flicker of the tiny LCD display screen of the piano input. I have downloaded various simple schematics from the internet (not displayed here) that claims to directly connect the MIDI port with an AUX/ RCA/ USB cables. I want to use that MIDI piano keyboard as a MIDI Input device for my Windows 7 MIDI apps. I have a standard USB (Male type) plug, taken out from a Standard USB Mouse, that has with 4 wires connected to it. Some of them also take input from my TEXT keyboard, but it is stressful for me to use the TEXT keyboard or the mouse as an input device, especially for inserting chords, and hinder fluency. In my desktop, I have a plenty of ROLL piano apps and MIDI Editor apps, which are asking for a MIDI Input device. I have a 32 BIT assembled Desktop computer (Intel Microprocessor, Intel Motherboard and an NVIDIA graphics card) running on Windows 7, that has several standard USB sockets (female type). it has a 9V power input (AC to DC adapter) I have an old type MIDI input device (Piano Keyboard Panel) which has a MIDI 'OUT' port (female type jack) that has 5 holes.
