+
+   USB_PWRSAVE_MODE_ONSUSPEND  Set USB peripheral in low power mode on suspend
+
+   USB_PWRSAVE_MODE_ONVBUSOFF  Set USB peripheral in low power mode when not
+   attached to a host. While this mode assumes that the internal voltage regulator
+   is used and that the VREGI pin of the chip is connected to VBUS it should
+   be safe to use given that VREGOSEN is always enabled. If you disable VREGOSEN
+   you must turn this off.
+
+   USB_PWRSAVE_MODE_ENTEREM2  Enter EM2 when USB peripheral is in low power mode.
+   On Mbed this allows the sleep() and deepsleep() calls to enter EM2, but
+   does not automatically enter any sleep states. Entering EM1 is always allowed.
+
+   Note for Happy Gecko, errata USB_E111: Entering EM2 when both the system clock
+   (HFCLK) and the USB core clock (USBCCLK) is running on USHFRCO will result in
+   a lock-up.
