I just discovered my budget only runs to a permanent marker for you to
write the instructions on the rim yourself ...

If it's not the scsi_bus_uevent problem, then no, it isn't.

The odd thing is that it occurs in the middle of USB initialisation from
the log:

Note the jump from 19 to 44 seconds.

There's another one here:

I'm a bit baffled as to how that could be SCSI related, but I suppose it
could be udev related somehow.  Perhaps turning on driver core debugging
might help (that's CONFIG_DEBUG DRIVER ... it depends on
CONFIG_DEBUG_KERNEL for activation).  Hopefully the verbose kernel logs
from here might tell us what's going on in the lacunae.
