If a file/directory on the USB drive is open and the drive temporarily loses power, then it will get assigned a new dev name when it is detected again.
Yes, this is the expected behavior of USB. A server at one of my client sites has /dev/sdf as the first available device name for USB mass storage. In the past they have got up to about /dev/sdl in use due to this issue. Before anyone says anything about umounting and being careful about such things, I sometimes have to accept that clients won't do the things I prefer and I just have to deal with it.

Incidentally, has anyone else found that usb sticks from the supermarket are unreliable? I have a new one which has begun showing up to 6% byte corruption in maybe 0.1% of files. (That failure is obviously not detected by rsync's default "quick check" algorithm which only looks for files that have changed in size or in last-modified time.)
It's always been the case that USB flash drives are somewhat unreliable at the best of times and often very unreliable. One thing that's worth doing is asking the more alert staff at the store whether they have many returns of the device you are considering buying. If you buy the device that most customers don't return then it will probably keep your data for a while. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
