How, from device information such as
/dev/bus/usb/006/015, I get a path such as
I have a script which detects that an USB device of a specific type (an Arduino) was plugged in. When the device is connected, it shows a bunch of data about it, such as the device path and name:
DEVPATH: /devices/pci0000:00/0000:00:13.1/usb6/6-3 DEVNAME: /dev/bus/usb/006/015
I want this first script to call the second one which uses the serial communication to interact with the USB device. For now, when I launch this second script by hand, I specify the device using the TTY:
./script2.py --device /dev/ttyUSB0
./script2.py --device /dev/serial/by-path/pci-0000:00:13.1-usb-0:3:1.0-port0
I want instead the second script to be launched automatically by the first one. For this, I need to map the device path and name to either the TTY path or the
How do I do that?
by-path, I notice the occurrence of
pci-0000:00:13.1 from the DEVPATH, but I see nothing related to
port0 (and I suppose I don't need to build the string myself and that Debian already has a tool to do the conversion for me anyway).
What I have tried:
lsusb -vdoesn't seem to show anything relevant: I suppose that it's much more low-level than TTY devices.
udevadm info /dev/ttyUSB0shows, indeed, the path
udevadm info /dev/bus/usb/006/015doesn't show anything related to TTY devices.
