It's definitely no optional. The TI part is designed for that. Not sure
about the others.
The HV bus is definitely optional - but most stationary devices - hosts,
docks,etc can supply that no issue
I would say that we will see big values on the HV bus from AC mains powered
devices.

Hi
The point that was made by the OP was that the new USB-C spec starts out with a
“3A default” rather than
500 ma. Since this stuff is just hitting the market, only time will tell how
the vendors decide to handle that
“requirement” with multi port gizmos.
With (now apparently obsolete)

The RPi doesn't seem to have a good reliability record, so that doesn't seem
like the solution.
Thanks time-nuts, what a resource.

Very few problems with multiple RPi cards here.
Most of the problem reports I've seen have been
I'd like to thank time-nuts for all of the information and advice I
received on and off list. I have stabilized my situation, I was able remove
all of the unused devices in the list (hidden) and now have many new tools
/ techniques to maintain the USB list.
I'm going to transfer most of the USB

USB-C will offer a number of things that I believe will be of benefit to
time nuts everywhere:
1) High current 5V up to 3A on every port

Hi
The one thing I would be a bit careful about is the power levels.
Consider an 8 port hub:
5V 3A from each would be 24A total. That’s pretty unusual. Most hubs
give you one or two high current outputs.
20V 5A (100W ea) on 8 ports would be 800W. That’s not going to be cheap.
Yes, the 20V

There are very few 8 port hubs and lots of 7 port
likely be changed.

Lately, I've been seeing blue screens that I think are caused by my
serial-USB adapters. Because I haven't updated by serial drivers since
before the driver update fiasco a while back, my feeling is that this
was caused by some other update.
Regarding the COM ports, here is a article on how
Hi
I’m not sure I can be of much help. I typically run several dozen serial ports
on various
machines without much trouble at all. They *all*:
1) Are under XP or Win-7 (no Vista)
2) Run FTDI drivers and nothing else
3) Get the drivers straight from FTDI
My case is so far off from your case

If its really number of USB devices, directly connected to the PC, then
it could be issue with overload of 5V bus on USB hub. It has certain
limitation.
As a workaround, you could try to use external USB hub with its own PSU.
