Well, the latest hub is a powered hub but I don't know about the driver. I'll probably have to wait until April 16th + 5 shipping days when I can load everything all over again.

I know that I was having issues with my Forerunner 305 loading but it could have been one of three things: the doofas operator not knowing how to switch devices in GTC properly, using a side USB port as you said, or just needing to re-load the SW. The last time I tried I used the powered hub and it worked like a charm but I had just reloaded the software. And for once, all the SW updates also ran like a charm.
