I was going to pipe up here, but I wasn't sure if it would be
interesting.  The Oxford English Dictionary has a first reference to
in this sense in 1875:

   5. orig. U.S.

   a. A defect or fault in a machine (esp. an electrical or electronic
   one), or in a process, etc.

   1875 Operator 15 Aug. 5/1 The biggest ‘bug’ yet has been discovered
        in the U.S. Hotel Electric Annunciator.

   1889 Pall Mall Gaz. 11 Mar. 1/1 Mr. Edison, I was informed, had
   	been up the two previous nights discovering ‘a bug’ in his
   	phonograph—an expression for solving a difficulty, and
   	implying that some imaginary insect has secreted itself inside
   	and is causing all the trouble.

Grace Hopper's bug doesn't get a mention.
