Cool!
I do have a (third gen) Focusrite Scarlett 2i2 but I was not able to use alsabat on this device.
Below is the USB configuration used to recognize this device as index 7 without grabbing anything by default ;-)
Perhaps you can share the tricky part to have alsabat run a roundtrip on this device ?
Regards,

Documentation for kernel 6.12 Guide to using M-Audio Audiophile USB with ALSA and Jack — The Linux Kernel documentation. (https://www.kernel.org/doc/html/v6.12/sound/cards/audiophile-usb.html)
As noted on that page, “the device initialization made by the Alsa driver in default mode may result in a corrupted state of the device”.
The following configuration was added to /etc/modprobe.d/
# USB devices
# This configuration defines as the first USB audio card a fake device that is never enabled.
# In theory, the index of the first USB device is replaced by a value of -2 to prevent other
# drivers from grabbing index 0.This behavior is not clearly documented and is avoided here.
