I don't want to see the question go unanswered but at the same time don't have much information to offer.
In Device manager Root Hub basically refers to the physical USB ports while the controller refers to the drivers. Thus, all that's normal. When it comes to the number, are you sure you only have 3 total? Most newer computers also have front USB ports, so look around on the front panel, on the memory card reader (if you have one), etc...a fourth one should be there.
As to Vista not recognizing anything you plug in, the only thing I can think of is to plug in a flash drive and then go into Computer Management->Disk Management through the control panel...see if the flash drive is recognized there at all. If not you could try reinstalling Vista, but if it's a drive compatibility issue then the only solution would be to wait for Intel to release an update.
Good luck.

Hello!
I've installed Windows Vista RC2 5744 x86 on my laptop but I'm having problems with USB ports!
On device manager, all ports are installed and drivers are up to date an working correctly but the main thing is Vista won't detect any of my USB devices!
Neither 3 Pen drives, neither Pocket PC and neither optical mouses!
I've tested on all 3 ports!
The laptop is Aopen 1557G and my USB controllers details are:
Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD - WHAT IS THIS?
Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 - WHAT IS THIS?
Intel(R) 82801DB/DBM USB Universal Host Controller - 24C4 - WHAT IS THIS?
Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 - WHAT IS THIS?
USB Root Hub - WHAT IS THIS?
USB Root Hub - WHAT IS THIS?
USB Root Hub . WHAT IS THIS?
USB Root Hub - WHAT IS THIS?
The wierdest thing is that I have 3 USB 2.0 ports, and appeard 4 USB Root Hub.
I don't really understand the meaning of these devices!
Please help me!
Hugs and Kisses to all!
