Windows 7: Force USB 3.0 ports to be recoginzed as USB 2.0 Ports

Force USB 3.0 ports to be recoginzed as USB 2.0 Ports

I know this sounds bizarre, and many not be possible, but bare with me.

I have a program that only runs on Win 7 that is used to program Solid State Logic Circuits (SSLC's) - (the developer is taking FOREVER to write a Win 10 Compatible version ).

To make matters worse, THAT program does NOT recognize USB 3.0 ports, and my new computer ONLY has 3.0 ports on it.

Is there a way to trick/hack/fool the OS (and thus the program running on it) into seeing the USB ports as 2.0 only?
Registry Hack?
Something Else?

FYI:
The USB cable that I use to program the SSLC's is 2.0 (on one end) only as well.

Your assistance would be greatly appreciated.

. . . I am guessing that I may be out of luck here.
No one knows if this is possible?

I'm guessing but I think like me most don't understand how a program knows whether a port is usb 3.0 or usb 2.0 or why it would care.

Usb ports don't care what kind of data goes through them. As far as I know the only difference between 2.0 and 3.0 is the (up to) maximum speed they work at.

To the best of my knowledge
in the Serial Port Era, programmers used to bypass Microsofts code library routines write directly to the hardware ports,
to speed up their programs. I don't know if that is the issue you are experiencing here, with second or third generation USB?

If the program really does not work with USB 3.0 it is likely due to some incompatibility, rare as that may be. If that is the case fooling the program is unlikely to be useful. If the program goes to the trouble of distinguishing between USB 2.0 and USB 3.0 it is likely because it needs to know. The fooled program would likely fail when it actually attempted communication or it would not operate as intended.

In any case I know of no such method and doubt it would be simple.

USB3 and USB2 are wired differently so if the software is expecting the signal on a set port this could be the issue, ( as you said developers used to "re-invent the wheel" at times to suit their ideas, I can remember many hours spent re-wiring Serial and Parallel plugs and sockets, to get live data from PLC's and data sources)

This may be of help USB 3.0 to USB 2.0 Internal Adapter Cable - 19pin to 9pin - Newegg.ca or similar (could be old link ), but would need a USB2 cable from the adapter to an external port either at the PCI sockets - A cheap Two or Four Port PCI USB2 card could also meet your needs and may not need the adapter. if you have space or even just a cable taken through any suitable Hole in the case.

Don't forget to back charge your costs to the software developer

Which ports are USB 2.0?
On an older computer that has a mix of USB 2.0 and USB 1 ports, is there a way to tell which is which? I seem to remember reading once you could connect a device to a port and look in Device Manager in the Enhanced USB section to see it listed, but I can't remember how to do it. Thanks
