I'm not sure whether it will help you, but I had similar problems when
I converted over to udev - I ended up using the following as the rule:

ACTION=="add", SUBSYSTEM=="usb_device", SYSFS{idProduct}=="8006",
SYSFS{idVendor}=="1604", RUN+="/lib/udev/tascam"

If I didn't do this, then udev called /lib/udev/tascam too many times
(more than once!).

I can't help right now, but I will have a look at this over this
weekend to see if it still works.
