udev!?!

I thought I explained how udev works briefly. I also suggested you
udevmonitor, you can also google. Neither UBI nor ubiattach nor any
other ubi utility should create any /dev device.

Sorry, I cannot provide more help. Try to dig this yourself - there are:
many ways. You can add printks to the kernel. You can even do echo 1
> /proc/sys/vm/block_dump and find out which process creates /dev
entries. Hey, be creative, do not wait that others will solve your
issues! :-)
