Hey, defecation occurs. :-)

The best indicator is the logo on the cable. It should say "USB 2.0" or
"Hi-Speed" or have the newer USB logo on it. Just looking at the
shielding isn't a guarantee.

"lspci -vn" will show you what's on the PCI bus. Make note of the bus
ID associated with that device, then run "lspci -v". Match up the
bus IDs and you'll see what's what. Example:
[root at prophead root]# lspci -vn
(snip)
00:07.3 Class 0c03: 1106:3038 (rev 16)
Subsystem: 0925:1234
Flags: bus master, medium devsel, latency 32, IRQ 5
I/O ports at c800 [size=32]
Capabilities: [80] Power Management version 2
(snip)
[root at prophead root]# lspci -v
(snip)
00:07.3 USB Controller: VIA Technologies, Inc. VT6202 [USB 2.0
controller] (rev 16) (prog-if 00 [UHCI])
Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
Flags: bus master, medium devsel, latency 32, IRQ 5
I/O ports at c800 [size=32]
Capabilities: [80] Power Management version 2
(snip)
Kernel 2.6 will give you similar stuff. You can find what's what on
each bus by using "lsusb".

Well, it found and spun up both this time. Congrats!

The commands I gave you above will help you identify the buses
themselves and which devices are plugged into each.

No problem.

Egads! Well, that's not bad. I have a buddy with an Audi RS6 (450HP).
Yes, it flies, but he's a maniac behind the wheel. I won't ride with
him anymore.
Plane stats:
1964 Piper Comanche 180 (PA-24/180), I'm the fourth owner
180HP, 4 cylinder Lycoming O-360-A1A engine
Hartzell constant speed prop
Retractable landing gear
Manual flaps (8, 16, 24 degrees)
IFR certified (avionics in the process of being updated)
Cruise: 120 knots (140 MPH, 225 Km/H) @ 8000 feet on about 9 GPH
She flies very nicely. I'm upgrading the avionics and the interior
(red vinyl and cloth--looks like a 1950s diner...yuck!) To sum her up
in terminology you'd recognize, mechanically she's "stout as a truck-
drivin' Sheila" and her exterior "is a right beaut!" ;-)
