This matches the strace log. The last two entries in the file show gphoto2 doing CLAIMINTERFACE followed by SETCONFIGURATION. That's not a good combination in the best of circumstances -- in fact it's totally illogical. And it's probably responsible for the lockup plus the further problems. I wrote a patch just a couple of days ago that might help. It's on my other computer; I'll send it to you on Monday. Ultimately the real fix will be to change the gphoto2 program.
