  I can't reproduce the problem on my system: mdevd-coldplug detects
all the USB devices. But it's a small system with no fancy hardware.

  What would really be helpful in diagnosing this would be:
  - your kernel version: if you're using an old kernel, maybe /sys
has a subtly different format
  - if you can find them, the contents of the directories in /sys
describing the hardware that is missed by mdevd-coldplug; in particular
    * whether they are accessible via a symlink in /sys/dev/char
(or /sys/dev/block, if mdevd-coldplug is also missing block devices)
    * the contents of their "dev" and "uevent" files
    * whether they have a "subsystem" symlink and what it points to
    * whether that hardware requires loading firmware
