Delphi 7 program need custom USB drivers for 64bit or implement WinUSB from manufacturer



What I have:


An old program written in Delphi 7 for WindowsXP. Program works with a hardware device via USB. It looks like CUSTOM drivers were writen for it to function and everything works great on WinXP and even Win10 32bit ONLY.




now days its hard to find a PC with 32bit OS and the program will NOT find the drivers under 64bit OS the software program runs fine it just CANT see the device plugged in, so cant communicate with it. (ive tried all the WinUSB, LibUSBk,0 or what not converters etc..... windows will locate the device with no issues BUT THE PROGRAM DOES NOT SEE IT)


What I need:


1. The Hardware uses a C8051F320 Chip. Sillicon Labs provides samples and has working Drivers for 64bit OS.

I would need someone to implement it into my software so it will function under 64bit OS. (samples are in VS,C++, my project is in Delphi7)

2. Write or Re-write the new drivers so it will work with my device under 64bit OS with the current PID/VID settings (Sillicon Labs has its own PID/VID and works via WinUSB) (its fine to run under 32bit environment but ON a 64BIT OS)

The Firmware for the chip 8051F320 is written in Assembly Language .asm I have no problem updating the PID/VID

IM attaching a section of the code that I think is responsible for the USB function since its CUSTOM written it has extra functions like READ serial # from device, plus do a PIN test (1-8) etc.... I am not sure if using the provided drivers WinUSB from manufacturer has these options or abilities.

there might be other call locations im not sure u let me know

I will NOT share the ENTIRE project source code, only sections of it so consider working with limitations

PS: references are made in Russian Language

Let me know my options.
