+	* usb.c:
+	  Moved the code from canon_usb_ready() to
 	  canon_usb_init() - canon_usb_ready() should send a
 	  'ping' packet to check if the camera is alive instead
 	  of doing stuff like identification and key locking.
 
+	* usb.c:
+	  Changed canon_usb_dialogue() to read responses in two
+	  passes - one that reads as much as possible that is
+	  divideable with 0x40 and then one that reads the
+	  expected number of bytes modulus 0x40. This is what
+	  the windows driver does and it appears some cameras
+	  (EOS D30) likes this better.
