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 up and running on my laptop and
connect it to an old machine with a built in serial port, as an attempt
to get KGDB running, but alas, KGDB does not recognize /dev/ttyUSB0 as a
valid device.

It looks like KGDB does not support the EHCI debug cable anymore,
although a crossover cable is available if that becomes an option.

Can someone in the group advise me on how to debug this issue? I was
hoping to get a back trace for you guys...

Thanks,

Brian
