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.
