Detecting 'floppy' like umass devices

[Daniel O'Connor]

A friend of mine handed me a USB flash key today that has 2 'partition' - one 
1.44Mb chunk pretends to be a floppy drive and the rest is a normal umass 
device.

I am wondering if there is any way of telling if a given umass device is 
a floppy drive (or wants to look like one) - eg I have a USB FDD which 
I imagine should fall into the same basket.

I note that you get wacky values from fdisk when you try and read partition 
table from them too..

On another note my USB floppy drive does 2k/sec in FreeBSD :(

It's one of these ->

I have a Dell Inspiron 8600 with a
uhci0: <Intel 82801DB (ICH4) USB controller USB-A> port 0xbf80-0xbf9f irq 11 at device 29.0 on pci0

I have tried a USB flash card reader which gets ~500k/sec.
