Thanks for the reply. Here's my comments.

Well, if I don't pass usx2yloader the card argument it just says:

  usx2yloader: no US-X2Y-compatible cards found

So, usx2yloader seems to be where my problem is. It doesn't succeed,
and I've never gotten any LEDs to light up on the US-122. At best I
get this:

  $ sudo usx2yloader -c 2
  usx2yloader: error in loading /usr/share/alsa/firmware/usx2yloader/us122.rbt

Could you tell me what version of alsa-firmware you have, and where
you got it? (That is where the us122.rbt file comes from.)

That seems to work. I figure out the USB bus with lsusb, and run:

  sudo /sbin/fxload -s /home/bkhl/src/usx2y-fw/usx2y-fw-0.1b/ld2-ezusb.hex -I /usr/share/alsa/firmware/usx2yloader/us122fw.ihx -D /proc/bus/usb/N/N

I hear a click and the program succeeds without any output.

I assume I have it, since loading the firmware works.

I have tried it by hand, too, in every order and fashion I have been
able to think of. hotplug gets exactly as far as I do. That is, it
loads the firmware correctly, but it fails to activate the device.

So, it all comes back to figuring out why usx2yloader fails, and/or
why it doesn't find the card at all without the -c argument.
