Hi Dave,
I've looked into this issue internally for you to find out a bit more about support for this kind of device. Unfortunately, we haven't yet been able to find a cable-free hub that will conform to the required USB standards and therefore no hub will definitely give full performance when used with USB DAQ. Some people have had limited success with this kind of setup in the past, but results vary and we have not found anything reliable as part of our own testing.
If the USB device works properly when connected directly to your computer, then our hardware and software is configured correctly. Beyond this, we can't recommend or support any hardware to perform that task. You'll need to use extension cables or a remote computer as you mentioned.
Sorry that we can't be of more help on this issue!
Best regards,
Tom
