If the question is "does that board come with an integrated USB hub or something similar that lets you hook up another gm5 board to it" the answer is no. If that's not what you're asking: I don't get the question ;-)

Sorry, what I am getting at is if more than one of these is built and to be used, once you have one connected to your computer can an additional one be connected to the first via USB or would each unit require it's own USB port?

Each would require its own

port.

Correct, each unit needs its own usb port on the computer.

Don't get smithy started about anything ;-)

edit: By "USB port" I mean a USB socket 'somewhere' as in "the gm5x5x5 module does NOT come with a built-in USB-thru or USB-hub"

btw has anybody ever come up with an open source usb hub schematic/board?

It's all good dude, I was apologising for editing your post; not attacking you for not editing it yourself. I need to be annoyed a few times in a row before I go there ;)

Meh! No need to apologise.

Our posts are there for you to edit!  ;)

Well, when we dont spot the error that is!

Jesus i almost made you sound like our slave.  :-\

is this USB 1 (12Mbps) or USB 2 (480Mbps) ?.

USB2 can also be 1.5Mbps.  ;)

USB2.0 simply adds the 480Mbps mode to the 1.5 and 12 Mbps (and does some minor enhancements).

Since the 480Mbps mode works completely different to both others device and host must negotiate about the protocol at a lower datarate and then switch over to 480Mbps.

For a good coverage about that topic see http://www.lvr.com/usb.htm
