cfbridge doesn't run properly

[rxdu]

Hi,

I've been trying to run cfbridge and use a joystick to control my CF2.

While CF2 is connected to the computer via USB, everything seems to be working fine. I can calibrate sensors, even arm/disarm and switch flight modes. So I think the firmware side should be working fine. But once I disconnect the USB cable, I couldn't get the cfbridge to run properly with PA radio. The command line output is either
"Waiting for messages...
error in transfer: LIBUSB_TRANSFER_TIMED_OUT"
or nothing at all. I can use my cellphone to connect to CF2 but I cannot control it using the screen touch pads. I think maybe it's because the quad is not armed.

BTW, I'm using Ubuntu 14.04 64-bit.

Any suggestions?

Thanks,
rxdu

I just found the python script "cfbridge.py" works, which means there is no issue in my hardware.
