rolandash Hi Rolandash, I am having USB issue for this onboard computer again. Now my raspberry pi cannot detect the USB device(mindracer). I followed the configuration for onboard computer and used a USB cable to connect raspi and mindracer with USB2. But when I use ls /dev on Raspi, it cannot show USB0. Of course when I run roslaunch mavros .. fcu:URL:dev/ttyUSB0:921600, it shows no such file or directory.
I haven't used it for more than 7 months since last time I succeed. Then I purchased a new mindracer (because my last one was fired due to short circuit) and assembled them. I even soldered another USB cable, it still cannot detect the mindracer. And raspberry pi is powered from a 5V BEC not from USB. Do you have any idea what is the possible reason? Now I have TFmini on GPS port, PMW3901 on U2 port (as you instructed in another post). Will those sensors influence it?
