Hi Karlito:

Looking at the "dmesg" output, I see messages that contain ttyACM0 and ttyACM1 (created when blackmagic probe is connect), but no mention of ttyACM2 or ttyUSBXX when the USB RF dongle is connect although the device is recognized by the kernel. Also I see that there two files device file created for ttyACM0 and ttyACM1 but none for ttyACM2 or for any ttyUSXXX under /sys/bus/........

If I remember well when I connect the back magic prob I get ttyACM0 and ttyACM1. Then when I plug the superbit RF I get the ttyACM2, and not a TTYUSB*.

Hello All:

I am very new to paparazzi auto pilot (Lisa/S). I am running paparazzi GCS on Ubuntu 12.10. When I plug-in the Superbit USBRF radio dongle to the usb port, the device is recognized by the kernel, but I do not see a /dev/ttyUSB0. So when I try to execute session for Flight address@hidden, I get the " Failure opening serial device: fd < 0 (/dev/ttyUSB0) " error. I am sure I am missing a device driver somewhere! The blackmagic JTAG probe works fine though and I do see the /dev/ttyACM0 device the blackmagic probe is connected to the usb port.

Can one of you gurus let me know what I need to do to get the /dev/ttyUSB0 device show up when the Superbit USBRF Radio dongle to the usb port ?

Thank you so much for your help in advance.
