USB external drives not recognized
My W7 64-bit machine stopped recognizing USB external drives and thumbdrives. I found a post on the internet about some systems not having the required USBSTOR.inf file. My machine was missing this file so I created one and copied the recommended text into it - file is attached. My machine will now recognize my Seagate FreeAgent GoFlex external drive (which it didn't before) but just gives the same 3-beeps when any others are connected.
Are there additional entries in the usbstor.inf file that need to be made for other drives? Is there another file that needs to be created or modified

SFC /SCANNOW didn't come up with any errors. No viruses. Any other ideas?

i would look first in device manager, to see if the usb is installed without errors.
if needed, update the chipset driver for your motherboard

Try running System File Checker to see if it can repair USB for you. Run SFC /SCANNOW and allow to complete. Run again if errors remain after the first run.
Restart your computer and test.
