As I said previously. I'm not one for giving up on problems so easly and I've found the fix for this one. (see link below for details)

Basically all you have to do, is use adb to connect to the Asus Transformer, then remount the system partition read write, push sqlite3 to the device and run a one line sql command.
then reboot the Transformer and just like that you get the use of channels 12 and 13 no problem.
