We have enough "nanny-ware" on our work computers to be annoying almost all of the time. While it's rare for this software to SILENTLY interfere with normal operation of software, there have been a couple of instances where some standard program managed to end up on a "non-trusted program" list and was (silently!) prevented from running. Software for manipulating device programmers and such is far outside the normal scope of "IT department" awareness, and it would not surprise me at all if standard nanny-ware were to prevent things like the "direct port access" drivers from installing or running or working, nor for the microchip SW to require something like that even for a USB-based device.
