Reply to "myDMX2 works in 1 of 2 laptops"

Ok, so I finally got my gear back after a show...  (BTW system worked fine on yet someone else's laptop)  I have set up another testing session, using a LED Mega Par as a test light, patched the DMX address/profile, plugged in the various components, dongle, waited a couple minutes, then started software.  And yes, it appears the software is still in Demo mode.  So I tried swapping out the USB cable, no difference.  Tried the second available USB port on the laptop, no difference.  However, I then tried plugging into the Hub port.  I have my Surface Book laptop on it's hub in my office, (a brick accessory that keeps Ethernet Cat5 and USBs connected, with a single charging cable to the laptop).  I tried plugging in the USB into the hub, and I got a connection and functionality.  So its down to the two USB ports on the Surface Laptop...  Any thoughts on why the loss of connection through these ports?
