typo. 63 is the number I intended in both cases. I am basically just inquiring as to the practical problems one might face when actually maxing out the spec, with 63 devices in one adaptor. You are correct - none of those multi-port adaptors actually have two buses. I am not sure if anyone has plans on a multi-bus adaptor. Since posting this question, I have received quite a bit of anecdotal evidence that suggests that actually having 63 devices on the chain at once is _very_ difficult. Most people report running into problems at around 20-30 devices. Power is also an issue, if the devices are bus-powered as opposed to wall-powered. ----- John Kozubik - john@kozubik.com - http://www.kozubik.com On Mon, 4 Mar 2002, James wrote: > > From: John Kozubik <john@kozubik.com> > > > > I still do not yet own 63 firewire devices, and so, once again, I am > > wondering if anyone here has ever actually connected 128 devices to a > > Huh?
