If you connect a USB device to your RevPi base module and want to access it e.g. via PiCtory, you may need a so-called “device path”. This device path specifies the location in the Linux directory structure where the device is currently located.
Important! Your device must not yet be plugged in.
- Start your RevPi and Login.
- Enter the following command:
ls /dev/ttyUSB* > /tmp/a 2>/dev/null
- Now plug in your USB device and wait about 5 seconds.
- Then enter the following commands:
ls /dev/ttyUSB* > /tmp/b 2>/dev/null diff /tmp/a /tmp/b
Your device path is now displayed. It is”/dev/ttyUSB0″.
0a1 > /dev/ttyUSB0
