Hello,
I am looking to use the Carambola for a project and have two questions.
Firstly I noticed in the dev board schematics there is a usb host/device mode jumper. Is there a example code of using a Carambola as a usb device that communicates with a pc in Control or Interrupt mode (Going to use the usb so an app on a pc can be used to configure the network)?
Secondly what endian mode the cpu is in? As I am thinking of using node.js which needs the cpu in little endian mode.

I don't know openwrt support usb slave mode or no.We have never used Carambola in this mode.
Carambola's hardware support usb slave 100%.

just had a read up on its in default linux kernel. I will probably using the GadgetFS mode which transfers data by reading and writing to a device file.
