Downgrade USB 3.0 to 2.0
I recentlybought a Inspiron 17R SE. Nice machine with 4 USB 3.0 ports. That sounds great but that is also my problem. I am used to work with VMWare on Windows 7 as host OS and XP as guest OS. That is fine as long as there are USB 2.0 ports available since VMWare can only handle USB 3.0 under Windows 7 if it is based on a NEC chipset. I would not have a problem if the machine had USB 2.0 ports.
Is there a way to downgrade to USB 2.0?

Thanks Mooly,
Reading your answer gave me some hope. That hope did not live long. Removing the drivers leaves an unrecognised USB device. Windows does not install a generic driver for it. Manualy selecting a generic driver does not work (was to be expected).
Thanks anyway.

I tried several things but was not successful. Since the problem I have is with VMWare and the Windows 7 USB 3.0 driver I tried something else. I upgraded to Windows 8 since this has a generic USB 3.0 driver that VMWare knows. First I thought that I could use Hyper-V but that does not support USB at all. So back to VMware and everything works fine now. A total different solution but it works. Thanks for your input

Before doing anything I would say first to make a full disk image backup. Then you can play as much as you want.
I wouldn't like to say for sure if either of these suggestions would work but they seem logical :)
In "programs and features" do you have a USB3.0 host application. If so you could try uninstalling that. Also you could try uninstalling the USB drivers from device manager and rebooting and let windows install generic drivers.
