Solution 1:
I found some posts here, apparently you can make it persistent with a registry modification: How to make SUBST mapping persistent across reboots?
Granted I haven't tried this myself...
Solution 2:
you can use this utility to solve the conflict. it is called USB Drive Letter Manager for Windows.
