Windows 7: USB weirdness

USB weirdness

Hi folks

I have a Win7 Pro x64 system that I built myself probably 18 months ago. A while back the system starting behaving oddly with USB devices (was fine previously). So if someone brings me a thumb drive and I plug it in, Windows tries to load drivers for it and always fails, and then the drive will not appear or be accessible. This is now always the case with usb drives, except with thumbdrives that I've been using since before this problem occurred - they still work fine. I know the drives people bring are OK because they always work fine if I connect them to my laptop (Win8 / Win10). So I then have to transfer files to my own thumbdrives and use them on my Win7 machine.

Often on boot or when connecting other USB devices such as graphics tablet or other peripherals, I get a message saying 'this device can perform faster if you connect it to a USB 3 port'. This always happens, even when it's connected to a USB 3 port.

Other things like a new Garmin GPS device would not work over USB on this PC even though I had the disk and drivers for it and spoke to support and tried everything. But it installed fine on my laptop.

Most weirdly of all, I have a TSST Corp SATA CD drive which has always been in the Win7 system and works fine, but on the weekend I had cause to temporarily move it to a different SATA port on the motherboard. When I booted Win7 later it tried and failed to install drivers for the CD ROM drive. I powered off and moved the CD Rom back to the original port. That seems to have stopped the automatic attempt to install drivers. But now when I put a CD into the drive, instead of the usual dialogue coming up about what you want to do with the CD, I just get a taskbar notification saying 'this device can perform faster if you connect it to a high speed USB3 port' - ?? It's an SATA CD drive - there's no USB about it. So I have no idea how or why that happens. But the drive still reads and writes.

It's worrying me that something's amiss with USB and it's frustrating not to be able to bring new thumbdrives into the system.

Any ideas what's happening or what I can do?
