D-Link DIR-615 rev E1-E4 USB port mod

1. Download svn source code
2. Edit file target/linux/ar71xx/files/arch/mips/ar71xx/mach-dir-600-a1.c (currently there are no 615e profile)
   • Add line #include “dev-usb.h” after line #include “dev-leds-gpio.h”
   • Add line ar71xx_add_device_usb(); after line ar71xx_add_device_eth(1);
3. For Barrier Breaker 14.07
   • Add line #include “dev-usb.h” after line #include “dev-leds-gpio.h”
   • Add line ath79_register_usb(); after line ath79_register_eth(1);
4. Run 'make menuconfig' and select platform/profile (atheros ar71xx/Dir-600-a1) and other options (usb-core,
   usb-storage, ohci, block-extroot, etc - all what you want)
5. Compile image and flash it to router.

1. Solder usb socket (use usb extender cable if you can't find vertical socket)
   
   
   
2. Solder usb power. DIR-615e use 5V power source so you can solder a inductance or even 000-resistor at L1 (Check input voltage first!).
3. Solder two usb data line resitors (r4/r5 - 22 Ohms).
4. Solder pull-down resistors (r2/r3). Use small 0805 smd 15k resistors (marked as '153').
   
   
   
5. Now check pcb... Twice! Power router on.......
   Wait until device boot, connect flashdrive and issue a dmesg command.
   
   
   If you did all well you'll get something like this:
