Well, the driver of the catweasel, even the latest is creating a floppy device for all the type of disks the cw can handle. I, for example, have 5 floppy devices among the catweasel itself in the hardware properties, one for the type of disk (ie: Amiga DD 880k, Amiga HD 1700K, C64 1541, PC DD 720k and PC 1440k). This is commented in the catweasel docs and will be substituted in the future with a less annoying mode of install those types. On the other hand, the catweasel support in winuae at the moment you could try the guide posted in this forum months ago, wich tells you step by step how to do it. And incredibly, the pc drive under winuae makes the clicking of the Amiga!. Support for joystick, mouse and keyboard wiil be added in the next version of winuae as well of direct disk support (with catweasel), without the need of the windows driver. I haven't tried the keyboard or the joystick port yet because i use my catweasel mainly for my Amiga 500 disks, so cannot say anything, but there are people in this board that had managed it to work.
If you don't find the catweasel under winuae tutorial posted here i could guide you through these steps.
Hope this helps.
See ya!!!!
