I could could not get the DDR Test Tool to connect to the USB Device. It is set to serial boot, and I can down uboot and linux using uuu.  However, DDR Test Tool kept giving me ERROR: Can't Open USB device. The following are the setting


* Connected to USB OTG

* Configure to Serial booting (I even verified that uuu can detect usb otg)

* Loaded init script



I wonder if I missed any steps
