For OS X, first do this:

  diskutil list

And then extract the list of disks (/dev/disk0, /dev/disk1, etc.). 
Then, for each disk, do:

  diskutil info <disk>

and then parse for "Protocol: USB" and "Ejectable: Yes". Then you have 
a list of mounted USB drives. Then to unmount a drive, execute:

  disutil unmountdisk <disk>

I'm not sure how to do it on Windows...
