Running a Poky/Yocto distribution on a HW platform with a Renesas R-Car. I have a USB peripheral connected and when I dmesg I get this -

[ 121.481489] usb 1-1: new full-speed USB device number 2 using xhci-hcd

I just want to monitor traffic on it. When I connect it to ubuntu, I can use screen ttyUSB0 4800 and can see the output from the peripheral which is sending data at 4800 baud. How do I do the same on this board? I dont see any ttyUSB show up under /dev/ nor can I use lsusb in this distro.

    What is the device? Presumably some sort of USB Serial adapter... do you have the `usb-serial` module available / built in? – Attie Jan 30 '19 at 19:27
  • You can always build `lsusb` for poky... it's in the `usbutils` package. – Attie Jan 30 '19 at 19:32
