USB FDD (Lacie Pocket USB FDD - Myfloppy3) not detected correctly

I am using vista ultimate, on Asus A8N-VM-CSM Motherboard. PC has no
floppy drive and I am attempting to use a USB Floppy drive (Lacie - Pocket
USB FDD Myfloppy3). Upon connection nothing happens, a quick check in
device manager indicates under USB controllers - standard openHCD USB Host
Controller with an (!) exclamation mark. Properties show:

-----
This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other
devices on this system.
Click 'Check for solutions' to send data about this device to Microsoft
and to see if there is a solution available.

Clicking check for solutions provides nothing. The USB ports on the pc
then fail to work until i uninstall all USB controllers from device
manager and reboot. The USB ports work OK with a flash drive I have, and
the floppy drive functions correctly on an XP PC I have. I can boot from
a boot disk if I have it in the drive whilst the PC reboots. I have
disabled as much as possible in both device manager and BIOS (onboard
audio, onboard VGA, etc).

When plugging the drive into an XP PC the drive is detected as a Y-E brand
device.

Lacie's website has no information regarding this, and the website for Y-E
indicate that the device should work under vista, as it is natively
supported by the OS Drivers. Maybe I'm looking in the wrong direction.

Can someone point me the right direction.

Thanks

Steve
