- +
-Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing. +

-sysupgrade /tmp/xxx.abc +

 +There is an unpopulated USB 2.0 port on the PCB. To use it, you need to short circuit R31, LB15, R35, R38, and R37 on the PCB: 
 + 
 +{{media:dlink:dir-853_a1:usb_mod.jpg}} 
 + 
 +The pin out of the USB socket (from the top to bottom) is: 
 +  - Vcc, 5V 
 +  - D- 
 +  - D+ 
 +  - GND 
 + 
 +This port should work on the official OpenWrt firmware, as ''mt7621.dtsi'' suggests that it is enabled by default.
