Re: USB driver and udev_run_devd

[Greg Huber <ghuber@vanteon.com>]

Kay,
Sorry, I lost the actual results when the system crashed again.
But the /etc/dev.d/default/ directory exists and is empty.

Changing it's name allows udev_run_devd to complete but
something, not visible with 'ps -elf' is running rogue, and
eventually crashed the system.

Another data point is that if I remove the device before unloading
the driver, everything cleans up nicely. I suspect that this is because
there are no endpoints to re-attach. The spin is probably triggered
by an 'add' event of subsystem type 'usb_endpoint' going through
the hotplug rules.

I tried adding 'usb_endpoint' to the hotplug rules but ended up with
3 rogue pam processes instead of /udev_run_devd./

Thanks for taking the time to look into this

Greg
