The firmware seems to have been removed from the Debian kernel. You can
download the firmware blob from git.kernel.org

wget -O firmware.fw 
"http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware-from-kernel.git;a=blob_plain;f=vicam/firmware.fw;hb=HEAD";

and try if copying it to 

/lib/firmware/vicam/firmware.fw

makes the firmware available to the driver.
