Andrea: This bit of codes ability to graph the connections would, if
translated to do the same for ones USB tree, be an informative, handier
than bottled beer, utility for linux. We do, or did have, a utility
called usbtree that did something similar with tabs and the text output
of lsusb, but that seems not to have kept pace with usb development and
has been dropped from many distros. I have a copy and its output looks
like this:
[gene@coyote bin]$ ./usbtree

Usable, but the graphic display would be even nicer.
That last, port 6 branch blows me away. I had ordered some "more better"
cables to reach some things in the basement, along with a 10 port hub,
all USB 2.0, with the cables purportedly to be 5 meters or 16 feet.
Which is about 4 feet short to reach the middle of the pile on that desk.
Imagine my surprise to see that they were 10 meters long when I opened the
$8.95 bag!
But that port 6 is one of those 10 meter, 33 foot, cables and its all
signing on as 480M connections. IMO someone has been to school and studied
up on radio tech involving transmission lines & VSWR to be able to pull
that off.
What I originally bought 4 or 5 years ago for that job, 15 footers, were
flaky at best at 12M. Needless to say, they will be retired as soon as I
am healthy again & feel like stuffing cable through holes in floor
joists etc.
I (& 3 others) arrived in Cinci to tear down & pack that transmitter
with the makings of a cold which has since turned into the real thing.
The transmitter was only about 12k lbs, which we reduced to under 1000lb
pieces we could move with a pallet jack, but we pretty well cubed out a
26' Penski van box & I have a few hundred lbs of copper stuff in the back
of my pickup yet. Both rode real well coming home. But we will need a
bulldozer tow to get that puny powered van to the top of the hill its
headed for.
Cheers, Gene
