IMO, this is the only right answer. Otherwise, the ID would be a 64-byte GUID and that would be the end of it.

  dd if=/dev/urandom of=~/guid bs=64 count=1
  od -t x1 ~/guid

  # the following step optional
  bitcoind sendtoaddress '1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt' '19.72'

The USB spec was developed twenty years ago, when the computer industry looked very different and the internet barely existed for normal people. It's a suboptimal decision perpetuated by backwards compatibility, nothing more.
