USB 3.0 Downgrade to 2.0?

I have a very expensive device that I am plugging in to a Win7 system with only 3.0 USB ports. The device is 2.0 and the computer is BSOD'ing all the time since the install of the device and driver. The vendor of the device says I should use a usb 2.0 hub on the PC because their device has issues with 3.0.

Does a USB port work that way? Can a 2.0 hub plugged into a 3.0 interface trick the device into thinking it has a 2.0 interface AND make the computer think the same?

USB 3 happily uses USB 2 devices. The vendor has said their device does not work properly and you should use a Hub. The problem is with the device, not Windows (normally) or USB 3 .

I recently had a similar problem. My device would not work on USB3 but did on USB2. Luckily I had a spare USB2 port.
You can buy a USB2 card from ebay.

I presume you mean it blue screens when the device is connected and doesn't when it is not connected.

In theory the USB 3 port should drop down to USB 2 when a USB 2 device is connected.  In this case it appears not.

You'll have to try the vendor's advice and see whether a USB hub can fix the problem.  But I'd also ask the vendor to recommend a hub THAT THEY HAVE TESTED AND KNOWS THAT WORKS.  Otherwise you could just be pouring more money into this for nothing.

may we know what device it is?
if it is an external disk - you may have other problems with it

That would be a way to 'force' the expensive device to 'see' a USB2 port.

Did you try the device on another W7 machine that has a USB2 port? Did that work?

Does your W7 machine have any front facing USB ports? Maybe they are USB2.
