What I am complaining about, is that the file management is going to the 
hardware level, when I believe that it should be operating at the 
operating system level.

If we use filezilla, or wget, they do not care what CPU or what brand 
and model of HDD's or whether the HDD's are mechanical or electronic, at 
the other end - they do their file operations, as far as I am aware, at 
the operating system level, and they do not care whether the network 
administrator at the other end, is wearing pantyhose or woollen socks, 
or leather soled footwear or rubber soled footwear.

For file operations between devices, it should be a matter of 
compatibility between the file systems software, not an issue at the 
hardware level.

So, going back to the original problem, it should have been a matter of 
whether Ubuntu 22.04 supports, and is compatible with, Android 15, and, 
can interface with it and its file system, and, not a matter of whether 
Ubuntu 22.04 has hardware drivers for all of the various devices that 
may be running different versions of the Android operating system.

If a person build a crystal set, it is not for the broadcasting radio 
station to determine what size and chemistry of every possible crystal 
that may be used in a crystal set, and, if you get on a bus at a bus 
stop, it should not make any difference to the bus driver, whether you 
walked to the bus stop or were driven to the bus stop, in a horse drawn 
buggy, or caught a diesel-electric train to the bus stop, or were pushed 
to the bus stop, in a wheel barrow. The question should be whether, once 
you get on the bus, you are compatible with travelling on the bus.
