 I don't know if this is relevant, but in the Linux kernel (which does
 not panic with this device), I found the follwing comments in 
 
 drivers/usb/storage/unusual_devs.h
 
 /* Casio QV 2x00/3x00/4000/8000 digital still cameras are not conformant
  * to the USB storage specification in two ways:
  * - They tell us they are using transport protocol CBI. In reality they
  *   are using transport protocol CB.
  * - They don't like the INQUIRY command. So we must handle this command
  *   of the SCSI layer ourselves.
  * - Some cameras with idProduct=0x1001 and bcdDevice=0x1000 have
  *   bInterfaceProtocol=0x00 (US_PR_CBI) while others have 0x01 (US_PR_CB).
  *   So don't remove the US_PR_CB override!
  * - Cameras with bcdDevice=0x9009 require the US_SC_8070 override.
