/usr/src/linux/drivers/usb/storage/usb.c, look for:

/* This is the list of devices we recognize, along with their flag data */

/* The vendor name should be kept at eight characters or less, and
* the product name should be kept at 16 characters or less. If a device
* has the US_FL_DUMMY_INQUIRY flag, then the vendor and product names
* normally generated by a device thorugh the INQUIRY response will be
* taken from this list, and this is the reason for the above size
* restriction. However, if the flag is not present, then you
* are free to use as many characters as you like.
static struct us_unusual_dev us_unusual_dev_list[] = {

{ 0x03ee, 0x0000, 0x0000, 0x0245,
"CD-R/RW Drive",
US_SC_8020, US_PR_CBI, NULL, 0},
