Hi,

2 years before all worked well, but now it doesn't and I tried a lot to find the fault without success.

What I want: Download logged dives from TUSA IQ-750 computer with the original cable (FTDI)

The Error: "unable to open computer"

What I tried:
1) check cable
2) check IQ-750
3) reinstalled FTDI diver (Mac OS ARM)
4) installed older subsurface version with libdivecomputer 0-8-0
5) tried other models (Oceanic Veo 2.0 etc)
6) tried to set a lower baud rate (did not work since libdivecomputer overrrites it) - the baud rate of 38400 seems quite high...
7) on Ubuntu same problems.

Here is the log:

And I attached a screenshot from subsurface.

I hope that anyone has an Idea. Loading dives via bluetooth from Heinrichs Weikamp OSTC+ works.

Thank you,

André
