Has anyone managed to find a USB hub that has more than seven ports,
that is not a multi-hub chip implementation (e.g. I have seen a 10 port
hub advertised, but suspect that the design is a seven port, with a four
port attached to one of the downstream ports on the seven port)?
I think this was asked before (JE?) - but can't find any response.
Anyone?
For interest, my assumption about the structure is based on Trendnet's
(http://www.trendware.com) numbering:
TU-400 - four port
TU-700 - seven port
TU-730 - ten port, not on website, see
http://www.cougar.com.au/Basket.cfm?PART=3816
As a secondary issue, would / should this count as two hubs in the
maximum topology depth? And can anyone provide a reference for why five
is the maximum depth - a quick scan of the USB spec only came up with
section 6.4.4 which talks about excessive depth, but doesn't say what is
excessive. I thought that it was driven by timing and the 5 metre
cables, but that wouldn't seem to apply in this case.
