Wanting to try this unverified answer for this unanswered question, but not without some kind of quick-and-easy backup. Thought copy-and-paste of the
/dev/bus/usb/004 folder would do the trick, but that doesn't work (yet), as its contents (001 and 002) appear to be "special files" which cannot be simply copied:
Can't copy special file
- Any idea how to quickly backup (and/or copy-paste) such files?
- Would you expect different behaviour of Command line vs. Nautilus/GUI ?
