How is it detected? As a gphoto2 device? What does scanimage -L show?

There have been some reports about problems with USB mass-storage.
Please have a look at the archive of linux-usb-users (and maybe
linux-usb-devel). See http://www.linux-usb.org for these mailing
lists. If you don't find anything, write to linux-usb-users. Provide
as many details as possible (cat /proc/bus/usb/devices, kernel
messages and when they do happen (plug-in, mount, umount)).

Bye,
