Hi

you can type in the logical name by hand in qjackctl rather than 
selecting one from the combo.
For example:

fedora15:~$ cat /proc/asound/cards
  0 [XFi            ]: SB-XFi - Creative X-Fi
                       Creative X-Fi 20K1 SB073x
  1 [UA25EX         ]: USB-Audio - UA-25EX
                       EDIROL UA-25EX at usb-0000:00:13.1-1, full speed
  2 [U25            ]: USB-Audio - USB Axiom 25
                       M-Audio USB Axiom 25 at usb-0000:00:13.5-2.1, 
full speed

and in .jackdrc


/usr/bin/jackd -P89 -u -dalsa -dhw:UA25EX -r48000 -p512 -n3 -M -Xseq
