We have a similar situation starting at H: (which stood for Home). This
was a leftover from the old Novell DOS network days where using higher
drive letters used up some precious DOS memory, so lower letters were
often used instead of something like Z:.
Using Disk Manager, I usually change the drive letters of my CD/DVD
drives and hard drive partitions other than C: or maybe D: so that they
start at something like F: or above, leaving E: and maybe D: unused. If
you have mapped drives at F:, you would need to go higher to avoid these
as well. This way, a new device will be assigned the unused letter E:
(or D

. After it is recognized, you can assign it a different letter,
and then the next time it is plugged in, it will be reassigned that
letter (if possible), so that E: is still free for further new devices to
use. Note that if you plug something into a different USB port, it will
be seen as a different device, and will not always be reassigned the same
letter.
From what I have seen, I think things go something like this:
If you plug a device in before a user is logged in, the network drives
are not mapped yet, so the network drive letters are free for the device
to use, and it does. If a user is logged in and has a network drive
mapped, the letter is in use, and usually a new USB device will not use
it - but, if the device was plugged in and used that letter before, it
will attempt to reuse that letter.
