Devices manager, unknown USB devices missing drivers, can't be found.
After refreshing a family Dell Vostro 3460 with new HD, new Windows 7 and a driver disk that was also provided by the (legit) Windows vendor), and after all the Windows updates, everything is fine in Device Manager except for three items, for which updated drivers cannot be found, and one for which no driver present at all. I don't know enough to know where to being looking for whatever is needed.
They are:
Universal Serial Bus (USB) Controller
Unknown device
USB2.0-CRW
The unknown might be the built-in card reader in the front? Just a guess, since no other USB devices are "attached" as for as I know.
The CRW is the one that shows up as having no driver present.
Can anyone assist me? More info needed from me?

Thank you. I did both, but but only one of the items disappeared. The
unknown device and the CRW are still there will the yellow triangles. Any further ideas?

In Device Manager and properties for the device, check the Details tab and select Hardware id from the drop down list. If one is shown, copy and paste that number.
They are not always shown but perhaps it will give you a clue.
