USB driver problems (NTKERN.VXD / error code 2)

Trying to get the USB ports on a HP Pavilion 4440 to work, have re-installed
drivers over & over but still no luck - when I look at the USB root hub in
device driver I get the message (not verbatim) that "NTKERN.VXD could not
locate the device driver - error code 2". Have done lotsa research on the
WWWeb and tried a few different suggestions but still no positive results. My
next step is to update the BIOS and see if that fixes the problem (HP does
have an updated, non-OS-specific BIOS available for this machine). BTW, the
USB controller/port is on the motherboard and is a SiS 7001 PCI-USB
Controller. Thanks in advance for any help!

You haven't told us what exactly you tried so it's hard to say what you
should try next. Maybe you should start from scratch, try this first:

HP and Compaq PCs - USB Device Troubleshooting

If that doesn't work then try this, (although I would think that
removing and reinstalling the HP usb.inf would do the same thing), won't
hurt to try:

Device Driver" Error Message
