Norcross,
Which drivers do you need for the PXI-8175? Most of the support for our PXI controllers installs with Measurement and Automation Explorer (MAX) if you have version 3.0 or above. There is also a
KnowledgeBase which has a couple of drivers you can try if you still get an unknown device or two after restoring the system and installing MAX 3.0 or higher (which installs with most of our device drivers, such as NI-DAQ or NI-488.2). If this does not solve you problem, please post here and we can discuss it further. Have a good day!
