I think the problem is that your Linux kernel doesn't know what the
camera is. You need to add a device declaration to the kernel source and
rebuild your kernel. Your camera should work once you are running a
kernel has the right declaration.

In the kernel file drivers/usb/storage/unusual_devs.h, add the following
(if you feel unsure of where to put it, just put it at the very end of
the file):

/* Pentax Optio 330/430RS digital still cameras */
UNUSUAL_DEV(  0x0a17, 0x0004, 0x0000, 0xffff,
                "Optio 330/430 RS",
                US_SC_8070, US_PR_CB, NULL,
