+===== Hardware =====
 ==== Opening the device ====
 Remove back cover, remove battery. Unscrew two screws, open case in the corner next to the ethernet port (there is a small triangle here). Push a screwdriver into the hole next to the battery (closest to ethernet port) and pull cover until it snaps open. Next push in the screwdriver in the next corner next to the battery.

+*GPIO_0 can be floating (i.e. resistors removed) during boostrap and the router still boots! //TESTED!!!//
 To make the GPIOs available via sysfs, the required ones have to be exported to userspace, as it is explained on a page of the [[http://squidge.sourceforge.net/gpio/|Squidge-Project]].
-Kernel modules occupying that resource need to be removed before (e.g. "leds-gpio" and "gpio-buttons"). In output-mode, voltage levels of the GPIOs were measured against GND, after the value 1 or 0 had been written to /sys/class/gpio/gpioX/value. In input-mode, the value of the file /sys/class/gpio/gpioX/value was read when the GPIO was floating (initial state), pulled to GND or pulled to Vcc.

-==== USB Issue ====
+==== USB Port ====
-A problem has been detected with the USB interface on the device. When connected to different models of serial adaptor, it functions for a few minutes then fails. This can be resolved by putting a passive hub in-line with the device. Voltage and current testing will be performed to identify why this behaviour occurs.
+Like other **devices using the ar933x platform**, this model suffers from problems when directly connecting USB 1.1 devices (specified for low speed or full speed; normally serial adapters). These problems can be circumvented by using a (passive) hub between the router and the USB devices. More information in the [[https://forum.openwrt.org/viewtopic.php?id=39956|forum]].
-**Edit**: Hi, I also tried with a webcam and make the router reset and even with a passive hub<-webcam also reset. But, then I remember to try with the battery on it(full charged) and doesn't reset, works perfectly, but if I remove the battery it resets again. Also with the USB cable removed and battery on it charged works good!
+**This problem can also be circumvented** by using an external powered USB HUB 2.0 //HIGH-SPEED//.
-Maybe a power restrictions from USB only?
