mounting a USB floppy drive with QNX 4.25 2011

Is there a way to use a USB floppy drive with QNX 4.25 Release 2011.

QNX 4 did support USB drives. You have to run the USB driver (I think called called Fsys.umass). There’s no such thing as Release 2011. Common versions were 4.23 and 4.25. 4.25 had sub versions. I think the last release was 4.25G or 4.25H. A running system can be a little tricky to figure out. Run “sin ver” and look at Proc. There will be other programs with version numbers that might be less.

This is a very minor point, but I’m going to disagree with you here. cleary shows a “QNX 4 Product Suite 2011.” And while that URL doesn’t show it, if you go into downloads there’s apparently an experimental 2015 release. (Never tried it.)

Of course, nothing inside the OS says anything about that. As you say, it’ll report as 4.25H (or whatever).
