USB: unusual_devs.h for 0x046b:ff40

American Megatrends did something wrong in their floppy emulator. It breaks
with both kinds of MODE SENSE which our stack sends. Alan and I tried a few
tweaks, and got LUNs sensed right, but US_FL_NO_WP_DETECT is still needed.

I set the firmware bracket to 1.00 exactly, in case AMI or Sun fix it with a
firmware update. Hey, you never know.
