Have you done that?

After a fashion, yes. I tried appending
--enable-native-access=ALL-UNNAMED
on the command line, but it made no difference.

Clearly, the restriction is new(ish) and there's no obvious reason to
think that's the right place put the option. The references I found on-line to this change date from 2025, the application was last updated in 2022 IIRC.

Thanks for writing!

It turns out there's a problem report that resembles mine at https://github.com/florentbr/OWON-VDS1022/issues/76
but it doesn't offer an explicit resolution.

At this point I have Trixie and Bookworm installs that don't connect
and a somewhat older Bookworm install that worked out of the box. So
far, the one that works is on a 33 bit Pi2.

Thanks to all for trying to help!

It only says it's a warning, not an error.

When something gives a warning that says 'this thing probably won't work',
it pays to pay heed, even if it doesn't immediately fail stop.

True, but if you $(SEARCH_ENGINE_OF_CHOICE) for it you will find that
there is a suggestion that some things may not work in the situations
that trigger the warning.

It's surprising how often clutching at straws yields results!

Indeed!

On the subject of trying random things, the one Java+USB weirdness I know
about (using the Altera JTAG stack, which is mostly C++ but some higher
level tools are in Java) is fixed via installing the libudev0 package.

Seemingly the JTAG tools try to use the bindings for libudev but an old
version and then try something less reliable if they aren't found. I've
found that symlinking /usr/lix/x86_64-linux-gnu/libudev.so.1 to libudev.so.0 fixes that - only just discovered there's a 'libudev0' package that does it properly.

I doubt this is the OP's problem though.

I made a copy of the working microSD, booted that and verified it could communicate with the 'scope. Then I invited the system to upgrade and
it made about 350 changes to packages. After that, the 'scope couldn't
be connected to.

So, clearly, an incompatibility has been introduced by the upgrade.

Is there some way to selectively update and revert when trouble strikes?
It isn't something I _have_ to fix, but it might be useful to know now.

Thanks for reading,
