this or another process has
initialized this device already
and an application tries to
open the device once more
or if a certain resource is
available only once but shall
be used twice.[-2102]

a software trigger mecha-
nism before the acquisition
engine has been completely
started. In this case a small
delay and then again calling
the software trigger function
will succeed.[-2106]

large or too small in that
context.[-2108]
