+        * USB 2.0 special considerations:
+        *
+        * 1. Since the core supports both OHCI and EHCI functions, it must
+        *    only be reset once.
+        *
+        * 2. In addition to the standard SB reset sequence, the Host Control
+        *    Register must be programmed to bring the USB core and various
+        *    phy components out of reset.
