Yes. That w
Hi Greg and Alan,
I just booted windows 10 to see if it can handle the setup and it can't.
The cameras lock up in similar ways to linux. A few frames display and
then they lock up.
It looks like some kind of hardware failure.
I'm going to take another machine with four USB 3.0 ports on it and se

Thanks Greg. I'm using the Sabrent HB-UMP3 which I would hope is related
to or derived from the Sabrent they mention in thewirecutter article.

Here's another crash. I include discovery of the hubs, cameras and even
the logitech keyboard and mouse wireless dongle.

Thanks Greg. It is a powered USB hub. The supplies have 2.5 amps to
spread across three cameras. One of the hub's ports uses laptop power,
but I'm not using that port.
The USB 3.0 spec (according to wikipedia) requires that each port be
capable of delivering 900 mA, so those power supplies seem a b

I just noticed that timing matters. If I bring the USB devices up one at
a time, with lots of time between power ups, things seem to initialize
better. And there are two ports that won't work much at all and two that
work until this failure occurs.

Thanks for replying Alan. I really appreciate it.
You asked what I was hoping to do. I have a six camera system that
crashes regularly forcing a reboot. I'm hoping to get more stability.
It's possible that the failure is software and not hardware or kernel,
but at any rate I'd like to know what th

I sent a message to the group yesterday, but I suspect it was too big
for it's own good and didn't make it to the list.
I'm attempting to debug a USB problem where multiple UVC camera causes
the USB driver to crash and shut down. All *HCI devices stop working.
I managed to get a USB serial port u
