Additional Information
Some vendors include a specific device driver for their instrument, so when Windows sees that particular instrument it associates that vendor specific driver with the instrument. MAX, however, uses the
ausbtmc.sys driver to communicate with USB devices.
If the end use of the device is not using NI MAX and the above steps did not resolve the issue, try communicating to the device in VISA Test Panels or LabVIEW to determine if you can communicate to the device. The
USB Instrumet Control Manual provides steps on how to test communication and run example programs. The device may be able to be used even if it is not appearing in NI MAX.
If the device does not show up in Device Manager, try re-install the NI driver associated with your device. (Ex, re-install NI-Serial for a USB-485 device).
