My query concerns a Casio Exilim EX-S770 camera which worked fine until yesterday. This device connects to the USB port via a dock which also serves as a charging dock. You put the camera (powered down) into the dock and press a button (on the dock) which puts the device into USB mode. Here's how it's identified by the kernel:
======================================================================= Nov 11 21:00:41 localhost kernel: usb 1-1: new high speed USB device using ehci_hcd and address 3 Nov 11 21:00:41 localhost kernel: usb 1-1: configuration #1 chosen from 2 choices Nov 11 21:00:41 localhost kernel: Initializing USB Mass Storage driver...

Is this thing totally bricked? I've seen 4 or 5 similar reports on the net about this camera. Is there a way to force the kernel to attach the device despite all these file-system errors?
