rog-control-center panics on GZ302: duplicate entry in aura_support.ron

[aregonini]

System info

• Device: ASUS ROG Flow Z13 2025 (GZ302EA, AMD Strix Halo)
• Distro: CachyOS (Arch-based)
• asusctl version: v6.3.8
• Kernel: 7.1.3-2cachyos

Problem

rog-control-center panics immediately at startup:

thread 'main' (230832) panicked at rog-control-center/src/ui/setup_aura.rs:148:55:
index out of bounds: the len is 7 but the index is 255
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace
fish: Job 1, 'rog-control-center' terminated by signal SIGABRT (Abort)

Root cause

/usr/share/asusd/aura_support.ron contains two entries for this model, one of
which has no layout name. This appears to be what causes asusd to expose
multiple aura devices (hence the "Multiple asusd interfaces devices found"
warning) and the GUI to read an invalid mode index (255).

Workaround (verified)

Deleting the entry without a layout name from aura_support.ron and
restarting asusd fixes the crash. Since the file is owned by the package,
the fix is lost on every update.

Same issue reported by another Flow Z13 user on the CachyOS forum:

Happy to provide more logs or test a fix.
