Dell Inspiron 700m USB slots; and cardbus USB not Working

Dell Inspiron 700m; USB SLOTS are not working. It was not working before I upgraded the bios. I upgraded from A01 to A07. Now the devices get power but don't initialize. (Plugged in an external hard drive; it spins as if it's working normal; but windows does not detect it) Have Windows XP Home Edition Service Pack 3. 1.23 GB Ram. I checked for any USB setting in the bios; only had one for USB emulation; which is on. Under Device Manager; under USB Controllers; there are no yellow symbols. The type shows as Intel 82801DB/DBM USB Universal Host Controller - 24C(+ a number or letter) It shows 4 of these even though there are only 2 usb slots on the laptop as well as 4 USB Root Hub. I tried uninstalling them; I tried choosing my own driver off a universal XP drivers disk; which installed a "Standard Universal PCI to USB Host Controller" but that didn't work either. I installed the latest chipset driver too.

Also; I bought a HI-Speed USB 4-port CardBus. (THIS DEVICE DOES NOT WORK EITHER) It recognized my micro sdhc memory card which has it's little USB connection. It also recognized a self powered external hard drive. But does not power or recognize my USB powered external drive; even if I use a two usb cable (one for power and the other for data). So it basically only half works. It gave me one error when I had my self powered External hard drive plugged in; and when I plugged in the USB powered Hard drive it gave me a blue screen and said  "BUGCODE_USB_DRIVER" The External USB powered Hard drive is a brand new WD Passport Elite; which works on my M1330.

I don't have a fast enough connection to download knoppix to test the USB.  I've tried disabling the Laptop USB to use just the cardbus USB. Should I just format this computer and start new?

    If you hadn't said what you said about Knoppix and download speed, that would have been my suggestion; this sounds like software/drivers problems and that angle should be investigated. A reinstall may be the way to go, actually. I'm not sure how windows handles USB in safe mode, but it's worth a try. Also, a SFC may be worth trying, if you feel a reinstall is a bit troublesome; you'll need the install disk anyway.

    I didn't wipe the computer; but I installed XP Pro on the same partition; just a new Windows folder. I had my usb thumbdrive in the USB; and when windows asked where to install it; it showed the thumb drive as a choice; I thought that was a good sign; in other words it works. So I went ahead and kept installing windows. To my dismay; when windows was done installing my thumb drive is still not showing. So; does this mean the hard drive needs to be formatted and windows has to be clean installed for it to work correctly; and/or why was I able to see my thumb drive only in the partition/ HD selection section of the install? Thanks.
