/If at first you don't succeed, try, try again. Then quit! There's no
point in being a damn fool about it. W. C. Fields./ I have gone far
beyond Fields admonition and the time has come to ask for help.
I'm trying to install Oracle VB on Linux (Mint) in order to run any
version of Windows so I might run Windows software to control external
IoT devices under Linux. They are controlled either directly via a
Serial Port, or via a USB adapter to Serial. These devices work fine
under any version of Windows alone, but I can't make them work from
Windows software running in a VB. (I've been fussing with this off and
on for months!)
Have tried a half dozen computers both old and new and they all behave
identically. Have installed the same IoT software on all of them
directly under Windows and it performs beautifully. Windows and Linux
alone work perfectly on those same computers (fresh installs on fresh
hard drives.) I'm convinced there is nothing wrong with any of the
computers and the mature IoT control software works perfectly without a VB.
I've installed the latest Oracle VB software plus matching Extensions
(direct from the Oracle site) countless times and it behaves the same on
all computers using different versions of Windows as GUESTS. Numerous
tests were run with VB using both Linux and Windows as HOST with
identical negative results.
(Sorry if this is getting long but I have to take out this frustration
on the keyboard...)
Here is what happens:
With either base OS installed, and a Windows GUEST installed in a VB,
with the GUEST powered OFF:
At the MACHINE level under SETTINGS and SERIAL PORTS I activate COM 1.
And set the USB Port to USB 2. After powering the GUEST ON these
SETTINGS are still correct as I set them, *but they are shaded out*!
Firing up the IoT software in this VB makes no contact with the IoT by
either the SERIAL or USB ports. However Windows Device Manager run at
the GUEST says both the SERIAL and USB ports are working properly. But
they are not.
For Example: The same IoT device that connects under Windows 10 (with
the VB turned off) does not work running Win XP (or any other Windows)
as a VB GUEST on that same computer with no other physical or software
changes made. That is as simply as I can explain it.
I keep feeling that I'm just one click away from success but don't know
where to click. I give up!
HAAAAALP! (Sorry I can't attend the Clinic tomorrow...)
