So, is there a way you can suggest to make it work under these conditions?

As per your inquiry-

I think that if I use .rbf files, I could manage to download them onto a target device (i.e. program it).

Transferring raw data from FTDI to JTAG pins is a managable task with a CPLD or FPGA, in my opinion.

Thanks again,

David
