Windows 7: USB Hub or USB card?

Now that's interesting - stereo mice.

Yeah, my right mouse is a scrollball mouse. But it is a bit awkward to click and scroll at the same time. For clicking I use my left mouse where I have covered the optical eye so that it does not move my cursor.

I am used to that setup from my scrollball keyboards that I used for years. But now I need a backlit keyboard because of my bad eyesight - and those do not come with scrollballs.

I didn't have any trouble with USB Hubs for years until I plug in a logictek webcam, or a digital camera, now I had a USB2 hard drive on a Hub screw up one of my USB3 Hard Drives. Hubs work great as long as you keep to keyboards, mouse, printers, scanners but if you have something you can't afford to lose don't hook it up to a Hub.

I'm not doubting you. But I'd like to understand how anything but a faulty hub could damage equipment. What is the mechanism to cause failure???

Also, I don't the hard drive issue in bold. I can understand strange outcomes by underpowering portable devices especially using passive hubs. Power considerations aside the USB standard allows for chaining 127 devices.

Also I have quite a few portable USB 2 HDDs and I always connect them to powered hubs. Imaged & restored many times this way.They have short leads to minimize IxR voltage drop and a direct connection would be a pain.

I certainly wouldn't want to damage an expensive camera by downloading photos via a (quality powered) hub! So again what would the failure mechanism be?
