Hi All,
A few points on this matter;
External USB hubs are not officially supported by NI or any of NIs USB devices, however, they often work with no problems. That said if you're going to use one I would strongly recommend using a powered one, I wouldn't be surprised if an unpowered one gave you problems.
Mireka and Ajeetraj, thanks for your posts, I think your two problems are different and unrelated, Ajeetraj's device disconnects while running, but Mirekal's device will continue running fine once it's connected. Mirekal; please bring your problem up in another thread and make sure you mention that you've already tried the solution from this KB as this is the first thing people will suggest.
Ajeetraj, what PC are you using specifically, and which chipsets does it have?
Many Thanks,
Kind Regards,
