INDI Library v1.9.1 Released (26 Jun 2021)

Bi-monthly INDI Library v1.9.1 is released bringing a few new drivers and improvements to existing drivers.

/dev/ttyUSB0 and /dev/tyUSB1 are not longer detected by indi

Instead of those, indi only shows _one_ Serial Device (/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0) which is mapped to /dev/ttyUSB1 ...

I always have to enter /dev/ttyUSB0 on my Focuser connection Tab an connect both manually ...

I'm using Stellarmate on RP4 with latest installed apt-get stable packages ...

Any suggestions?

Can you check what in /dev/serial/by-id ? is it only one device? it could be due to two identical devices. What does lsusb show? and how about ls -l /dev/ttyUSB* ?

The funny thing is, that i have the same behaviour on 3 different RP4:

stellarmate@stellarmate:/dev/serial/by-id $ ls -lsa

stellarmate@stellarmate:/dev/serial/by-id $

EDIT:
the by-path contains both:
stellarmate@stellarmate:/dev/serial/by-path $ ls -lsa

So it seems that the by-id is not generated correctly?

Ok I think Linux kernel does not create symlinks for identical devices... I think INDI should fall back to using ttyUSBX in case such a discrepancy exists... working on it.

Ok please re-compile from GIT and check if that solves the issue. Basically, not it falls back to ttyUSBX ports if it detects a discrepancy.
