FTDI on WGT634u Running OpenWRT Backfire

In this post I will document the modules that installed to get a WGT634u running OpenWrt Backfire to recognize a DFRobot.com FTDI (http://www.dfrobot.com/index.php?route=product/product&filter_name=ftdi&product_id=147).  In order to trouble shoot this better I am connected to the router via a usb to serial TTL cable.  Instructions on how to build one can be found here.

First we need to install the USB modules. This router seems to support usb2 and ohci so these are the ones that I installed.

opkg update
opkg install kmod-usb2
opkg install kmod-usb-ohci

Note: You can use the following command to see what usb is supported (uhci or ohci):

cat /proc/bus/usb/devices

Next we will install the modules for the FTDI:

opkg update
opkg install kmod-usb-serial-ftdi

Note that when you plug the FTDI into the Arduino you should connect the tx to tx, rx to rx, and gnd to gnd. It seems that the usb on my router does not have the output to power the Arduino through the FTDI so I am powering it separately with a 9v DC adapter.
