Sounds similar to my experience. Normally my internal 4 slot memory card=20
reader is assigned devices da[0-3] and when the USB memory stick is=20
inserted it comes up as da4. If the USB stick is present on booting=20
then it appears as da0 and the card reader is da[1-4]. So it looks like=20
occupied slots are given priority when numbers are assigned at boot=20
time.

=2D-=20
