I have been trying to solve this issue for days, and looked up all other threads with similar problem but nothing is working. Please read this to the very end before you comment.

I have an IBM T42 Windows XP and recently began receiving an error in the taskbar saying that my USB device is connected to a slow USB port and that it would run faster if I connect it to the USB 2.0 port instead. I only have 2 USB ports on my laptop, and I get the same error with the 2 ports. When I click on the error I get this screen:


In the Device Manager window, there are no error or yellow exclamation marks. I noticed however that there are 4 USB ports in there. Through trial and error, it seems that only the 3rd one is the one connected to my USB ports (highlighted in blue in the picture).


I tried several times updating the drivers, uninstalling and reinstalling them, and even manually downloading a driver and specifying the exact location for a driver update. Every time the driver update utility informs me that there are no drivers more recent than the one I have on the computer.

When I looked into driver details, this is what I found:

The USB 1.0 driver files:

The USB 2.0 driver files:

So my question is as follows: Is there a way to manually change the driver files? Or is there a way to remap the USB drivers to the appropriate files?

Thank you and I really appreciate your help. This has been a real challenge and I'm really hoping to get some valuable insights into this issue.
