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