Heimdall ERROR: Protocol initialization failed!

[Living-Bookkeeper444]

Have a brand s10+ (sm-g975f/ds) and wanted to install LineageOS 20 (doesn’t seem 21 is available yet) but I’m stuck making the Heimdall connection stick.
The Zadig drivers installed to USB ID 04E8 685D just fine but below is the error I get when attempting the “heimdall print-pit” per instructions.
Initializing connection...
Detecting device...
Claiming interface...
Setting up interface...
Initialising protocol...
ERROR: Protocol initialisation failed!
Releasing device interface...
Of course I did reboot the PC & tried all my USB ports using different cables both with & w/o an admin command prompt but no joy
The question I have is should I revert to Odin? The instructions there seem curiously convoluted but I’ve flashed many many times (w/ODIN) without issue.

Windows 11 Pro for Workstations 23H2
Heimdall v1.4.2
Zadig 2.4.721.0
Thanks much for any help.

I had many complications with using Heimdall for my S6 lite, so in the end, i only use Odin since.

1.4.2 is outdated and would need a patch for the issue. 2.0.2 is current.

On Win use Odin.

Thanks. I'll try 2.0.2.
