As a 32-bit two's-complement negative integer, -2 in binary is
11111111111111111111111111111110.  This means that the snd-usb-audio
driver is allowed to attach to any index except 0.  (If the USB driver
is loaded before the HDSP driver, you lose.)

Do not use the index= option.  Always use the slots= options of the snd
module instead.

Remove the index= lines, uncomment the last line, and add the
snd-virmidi driver where desired.
