[PD] comport + usb hub issue

[crinimal at gmx.net]

hi. my 2 cents:

* try using USB cables that have EMI filters in them wherever possible.
* some USB hubs are more prone to EMI issues than others. I used
logilink UA0003 without issues (apart of a crappy mini usb connector).

also try using a powered usb hub if you're not doing that already...

happy usb patching! :)

It seems that only unplugging and replugging in the usb hub's usb cable will refresh the connection (after sending the connect message again from the patch).  I am running the project on an older macbook pro with osx 10.8.5.  Is this a usb hub problem (radioshack brand) or should I be looking at something else?
