I want to note that I am an official user of drivers from Arca Noae. I paid them for a subscription and expect them to work.
If they aren't working, open an incident in the Arca Noae Mantis Bug Tracker. I suggest reporting only supported configurations. I will also note, that the USBXHCD driver is a PREVIEW version, and is not actually supported. Be sure to READ the docs. If you need an updated driver, but have not renewed your subscription, don't expect freebies.
Actually OS / 2 has not been supported for a long time and is rather not alive.
Arca Noae has legal authorization to distribute patched versions of OS/2 software (the ArcaOS kernel is one example). NOBODY else has that legal authorization, including the OS/4 group (even eCS was not permitted to do that). If Arca Noae started to use stuff from, or produce stuff for, OS/4, they could be shut down. It is in their contract with IBM.
The OS / 4 kernel has been seriously updated; significant errors have been removed from it; it is significantly faster than the OS / 2 kernel. In the OS / 4 kernel, virtual machines run significantly faster. And in some modern systems, the OS / 2 kernel does not work at all and the system starts only with OS / 4. Not only that, some Arca Noae drivers do not work on the OS / 2 kernel, but they work on OS / 4. And most importantly, the OS / 4 kernel is supported and updated regularly.
Arca Noae drivers are supposed to work on machines that are running supported versions of OS/2, If they don't, report the problem. It may not be fixable, but I guarantee that it won't be fixed if you don't report it. The support group does insist on supported configurations (no PREVIEW software, or "unknown" operating systems - like OS/4). They don't have the resources to try to do otherwise.
Perhaps the OS/4 group will support their software. The biggest problem with OS/4, is that the legal status is far from clear. If, as they claim, it has been developed in a clean room, that may still not pass the legal system. Until it has been judged by the legal system, the status is unknown (and I doubt if the OS/4 group could afford the legal fees, so they would lose by default. So would Arca Naoe, if they break the rules of the contract). Use OS/4 if you like, but don't expect Arca Noae to even recognize that it exists. They just can't take the chance that IBM will take them to court.
If we abandon development that ensures progress, then there will be much less movement in our cemetery.
There is movement. The biggest problems, at Arca Noae, are too few good programmers, and not enough money in the pot. I have no idea how OS/4 is funded, nor do I much care.
Doug, you are still sitting on a high horse.
As we all know there are limited resources and limited money.
Eternal repeating does not change anything nor make things better.
Reading the docs tell: USB 3 is ALPHA Code. Well done after 4 Years of Development! Once there is a problem and one can not solve this, it may be time to go for help or open oneself. Naming Lars and Wim are only two of those who might have been able to assist (assumed and provided they would have liked to) or help. So the argument "Limited Resources" does not count when it comes to USB 3. The reason for this is another one:
ArcaNoae decided to go the other way, making what is left from OS/2 to some kind of closed source.
And in addition: why have there never been - as suggested before - some kind of open beta for USB 3? Instead there is some kind of open Alpha here with 5.05 now, a product that is for sale?! But - who cares - it is like it is.
I remember the kernel versions I got from Holger, based on the 14.106 Kernel and in addition his patches for WPS files. Even if I do not really understand what technically he has done - the results counted. And his kernel and WPS patches did lead to a much more stable OS/2 (or ArcaOS) than I have had ever before or after.
I might make a shot in the dark, but I would guess some of his - you may would call it from your "Lord Protector for the Holy ArcaOS" position as some kind of illegal - changes have somehow find their way into ArcaOS.
So ist the OS/4 kernel - if you like it or not, it does provide usefull functions and abilitties the AOS Kernel miss.
In the end results count: ArcaNaoe is basically doing a very good job.
USB 3.0 is far from working stable, it is some kind of Alpha software.
ArcaOS is getting more and more closed source.
"Protection Policy" for Software is contra productive in our days. It will destroy what is left of the "OS/2 community"
Suspect others - like OS/4 team - without a real proof as "illegal" is not OK and sounds like narrow minded thinking!
In December we will held our OS/2 User meeting in Cologne, we will see if there is enough demand for a meeting in 2021 or if it will be the last. We are waiting for the DE Version for some years now, and motivation (and the age/time) is running out for most of us.
