Unless the fellow who drew the schematic is wrong, the + side goes to pin 2
on the User Port connector and the - side goes to ground. The curved side
of a capacitor symbol specifies the - terminal. If it's a nonpolar cap,
then two straight lines are commonly used. But since pin 2 appears to be
+5, the schematic is correct in that respect.
