port/hub in case of power surge.
2. Soft Reset (9. Soft reset (Default Settings) on page 42) and verify if USB device is
recognized.

or USB is recognized without Yellow bang.

drawn (0.9A) from USB port than USB 2.0 device (0.5A). As a result, identify USB
charging port to be used for charging a USB device, or an external AC power adapter
may be required for an external USB storage to work properly.

ports are functional.
7. Test USB device on a veried working computer to make sure USB device is not
malfunctioning.
