Re: ibusbk claim interface fail after 32 loops

if it can help here is a partial log  where we can see some successful
open/close  before last failing one

Quit (expect signal SIGINT when the program is resumed)

Strangely error message says fail to claim interface "0" when actually I 
claimed interface 1 ???
Is the "[84] Storage to process this request is not available." an error
coming from libusbk ?
