[Alberto Franches]

I have installed calibre 0.6.55 to my computer, which runs Windows XP Professional, so that I can use calibre to transfer ebooks to my new iPHone 3GS. I want to get most ebooks by downloading to my computer and copying over using the USB cable, not by downloading direct to the iPhone.

Unfortunately, calibre recognizes USB ports while being used by USB keys but does not detect when those same ports have my iPhone or Blackberry attached to them. When I plug the iPhone in Picasa can tell, iTunes can tell, but calibre doesn't have a clue.

I tried repairing calibre, reinstalling it, changing my firewall settings to expressly allow calibre, changing the setting from iPhone to default, hooking up the devices after starting calibre, hooking up after starting calibre, and restarting my computer. None of it makes any difference: so far as calibre is concerned no device is connected.

Yours in frustration,

Alberto
