USB 3.0 not universally backwards compatible

I am not liking USB 3.0. All my stuff is 2.0, even relatively new stuff. Over half my 2.0 stuff won't run on a 3.0 port. So this makes half my USB port worthless for all intents and purposes. Is there a way to dumb down the 3.0 port drivers to be more accepting of 2.0 devices. I have this problem with desktop and laptop motherboards.

What motherboard we talking about ?
AFAIK, if they have the USB 3 logo, then that means that it must support all USB devices...or they lose their license.

The main one is my new Dell Precision 4600 laptop. Lots of stuff won't work on the two 3.0 ports which is half the USB ports on the laptop. I have an ASUS motherboard that has similar issues with the 3.0 ports.

What's the Asus board? The Dell should be using a NEC/Renesas chip. All I can say is I just worked on a N5110 with the same USB 3.0 chip, and it worked with a USB mouse, KB, 2 Sandisk thumb drives, and JMicron-based USB/ATA adapter just fine. Now, as far as Windows goes, I only know it saw one of the thumb drives :).

I've had problems with some of the USB 3 ports on HP laptops. I don't think it's a backwards compatibility issue, but rather immature chipsets.

Ok well it seems that most of the problems are with the Dell. I could not run one of my Toshiba hard drives on any of the Dell ports, 2.0 or 3.0. However, it runs fine on everything else I have tried. Even my wife's little baby Acer craptop. It would have to pic the hard drive that had all the movies on it for watching on trips.

I've not yet had an issue. Using a western digital 2 port PCIe card, a Jtech 4 port hub, and a Transcend card reader. They all work fine.

Everything else I own is USB 1 or 2 and they all work fine thru the hub as well.

My laptop has a single USB 3 port and I havent stuck everything in there but the few things I've tried always work.
