Updated Jan 9, 2018

Issue Details

Are NI USB data acquisition devices compatible with USB 1.1 or USB 2.0?


All NI USB data acquisition devices are compatible with USB 2.0. Three speed classifications exist in USB 2.0: low speed (1.5 Mb/s transfer rate), full speed (12 Mb/s), and high speed (480 Mb/s). NI USB data acquisition devices fall into the high speed and full speed categories. Full speed devices, while compatible with USB 2.0, also work with USB 1.1 hosts without any decrease in transfer rate. However, USB 2.0 high speed devices will be limited in speed if used with a USB 1.1 host.
