I agree, but then I would have had to add the code to examine the error
code structure. By setting QUSBPrv to 0 you'll get an escape returned to
the application (which will make it very clear that you have an error).

How is this "escape" detected? In my experience, having bytes
provided set to zero simply causes errors to be ignored with no indication
either to the program or to the joblog.

PS - you don't have to set QUSBAvl to 0. The APIs will do that for you

when

there is no error (and QUSBPrv >= 8.

Apparently, not all of the APIs are so nice. I have run into the
situation where a "ghost" error was being detected from an API where there
was not actually an error because the error code data structure still had
information in it from a previous API that had reported an error. When I
started setting the bytes available to zero the "ghost" error detection
went away.
