I have connected two arduinos to /etc/ttyUSB0
and /etc/ttyUSB1
.
Only one is visible in Arduino IDE. Why and how to force second?
UPDATE
$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Jan 6 23:32 usb-1a86_USB2.0-Serial-if00-port0 -> ../../ttyUSB1
I.e. it shows port, which IS NOT SHOWN in Arduino IDE (only /dev/ttyUSB0
is shown.
ALSO
I can see both ports if run arduino
with sudo. Should I run it with sudo?
Permissions are same
$ ls -l ttyUSB?
crw-rw-rw- 1 root dialout 188, 0 Jan 6 23:26 ttyUSB0
crw-rw-rw- 1 root dialout 188, 1 Jan 6 23:39 ttyUSB1
ls -l /dev/serial/by-id
show?
