when I made a fresh CCRMA+FC3 install some time ago, hotplug 
worked out of the box. 
My (propably self modified) modproble.conf currently has this
relevant entries:
------
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
install snd-usb-usx2y modprobe snd-seq; modprobe --ignore-install snd-usb-usx2y nrpacks=1 index=1
alias snd-card-0 snd-via82xx
options snd-card-0 index=0
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx
------

Yes, see above. Its the "nrpacks=1". Also you need a modified jack.
Well its only jack's alsa-usx2y driver that needs tweaking.
Attached is the patch, which I've also sent to the jack-guys.
If you have that modified jack installed,
make sure you specify the alsa-pcm device like this:
	$ jackd -dalsa -dhw0,2
the important part is the ",2".
qjackctl has a convenient dropdown menu to choose "the right thing".

Doc is currently "read the source" only.

Last time i checked the STOP/PLAY Buttons worked.
Not sure about the rest.

   Have fun,
