da0 takes a long time to appear

Hi,

I recently had to replace the enclosure of an external USB harddisk (WD
E1U10000E Elements). With the new one (Trekstor DataStation maxi n.u 3,5"), it
now takes over one minute between the detection of umass0 and da0. After that
it works fine.

Is this delay due to the hardware or is the kernel at fault?  Any debug
information I should provide?  I'm running head r234133.
