Over the years I have been buying dozens of 8/8/8 Phidget IO boards.
These are used in a "Control Box" for a Windows application that I market to a specific user group.
Recently I bought 3 new ones and started constructing the "boxes".
However, when I connect the new boards to my development PC, I get an error message from Windows stating that "USB device not recognized".
But if I take an older box (with an older 8/8/8) it works OK. (connected the exact same way)
If I crawl under my table and connect the new 8/8/8 directly to an free USB port on the PC, it gets recognized and works OK.
It seems now that the new boards will not work when connected via a USB hub, but seem to work when they have a "private" USB port on the PC.
This is definitely a new (and most unwanted...) behavior!
Has anyone else noticed something similar?
