gphoto2 cannot detect camera after 13.10 upgrade

[Daniel Barrett]

I just upgraded from ubuntu 13.04 to 13.10. gphoto2 can no longer detect my Canon S100 camera. I plug it in via USB, and no messages at all appear in /var/log.

$ gphoto2 --list-ports | grep usb
usb:002,003 Universal Serial Bus
usb:001,003 Universal Serial Bus
usbdiskdirect:/dev/sdc USB Mass Storage direct IO
usbscsi:/dev/sg4 USB Mass Storage raw SCSI

$ gphoto2 --auto-detect

$ gphoto2 --debug -P

"sudo lsusb" does not show the camera either.

OK, I got my camera recognized by using a different USB port. (My USB switcher was having a problem.)

Now gphoto2 says:

$ gphoto2 -P
*** Error ***
An error occurred in the io-library ('Bad parameters'): No error description available
*** Error (-110: 'I/O in progress') ***
