Doug,
Does this same concern apply to Banana Pi?

Since the question was asked on this list I assumed it was about Allstar and
not the Pi in general. The Raspberry Pi is a perfectly good single board
computer just not for Allstar. That is why we moved to the Beagle Black.
Since the Black is now in full production there is no problem getting and
using it. It costs $20 more but it is worth that much more in what it does.

The Pi runs its Ethernet on the USB bus and that causes problems when you
are trying to run both Ethernet and USB simutaneously. It is also a slower
and older version processor than the Black. The B+ just adds a built-in hub
to expand the USB to four instead of two ports. The problem we had was data
not current capability.

I'm curious to understand a little better, if you'll indulge me.  The
announcement page 
<http://www.raspberrypi.org/introducing-raspberry-pi-model-b-plus/>  claims
that the B+ has "better hotplug and overcurrent behaviour" with regard to
USB.

Most of the USB issues I've heard of with the Pi seem to relate to power and
current, and it would seem that it's being claimed they've been addressed to
some degree.  Are there different USB issues, or did they fail to address
them sufficiently in the B+?

Thanks,
Eric
