Thanks for the reply Darren,
I am trying my best to take this all in. I am fairly new to the scene. I
was ready to upgrade to the new kernel per this

I'm afraid some of the tasks that you mentioned above is beyond my current
skills. If you would be kind enough to elaborate lil further, Im sure I
would be able to read up on it and provide you with all the info needed.

In addition, i was able to find the required .ipk file for a manual opkg
install (might be bad/naive but im trying everything). As expected it
failed due to two main depends:

   - kernel 3.10
   - kernel-module-usb-core

So i based on my knowledge, the kernel upgrade would give hope.

Thanks for your time!
