>sigh< This was an annoying... "oh, that's going to be a problem" moment.
Task creep. Always a bad thing.
I've got my Homeseer instance running on an Intel NUC. Been quite reliable for ages. But always noticed "odd things" about USB devices connected to it. Long story short, the chipset is limited to 96 logical devices on USB, and lots of hardware may require more than one of those device addresses. Couple that with the whole USB2/USB3 hub overlap... and you run out of addresses pretty damned quick.
My plan to temporarily use the machine to handle moving a bunch of data around on some external USB drives tossed a serious monkey wrench into the USB config.
These are probably the most informative of the many posts I had to wade through last night:

So, yeah, USB on some chipsets is more limited than you might realize.
