I'll have to instrument something to run early enough in rc.sysinit or
from the initrd so that this can be captured. The point in time where
the device is disconnected is just to early.
Would an initrd generated without usb support allow me to load the
modules one at a time to get this set up so I can use usbmon you
think?
Good thinking, but I think it might be easier just do rmmod uhci_hcd
than rebuild your initrd.

sierra and usbserial is blacklisted, and the device still get
disconnected.
Well, I said that because the original dmesg you posted had drivers
involved. I may be wrong about it though.
