Support request: Lexar Ares DDR5 6000 MHz RAM RGB not detected

Description of Bug

OpenRGB does not detect Lexar Ares DDR5 6000 MHz RGB RAM modules.

Other RGB devices such as the MSI MAG Z790 TOMAHAWK WIFI motherboard and Logitech G915 keyboard are correctly recognized, but no DDR5 DIMMs appear during I2C detection.

The Lexar RGB lighting works under Lexar’s own software, so the hardware controller is functional.
This issue persists even when running OpenRGB as administrator and with “Shared SMBus access” enabled.

Steps to Reproduce

Launch OpenRGB v0.9+ (1.0 rc2, commit 0fca93e4544f943d4d7ec8073dba4e47c18ef54b, build date 2025-09-14) as Administrator.
Ensure “Shared SMBus access” is checked in the settings.
In BIOS:
- SPD Write Disable → False
- Mystic Light / onboard RGB control → Disabled
Run detection (automatic at startup or via “Rescan”).
Observe that no DDR5 DIMMs are detected under “I2C DIMM modules”.

Expected Behavior

Lexar Ares DDR5 RGB modules should appear as SMBus/I2C devices in the detection log
and allow at least basic RGB control (static color, brightness, etc.).

Attached Log

Excerpt from the debug log during detection:

| Detecting I2C DIMM modules |

(no DIMMs detected)

| Detecting I2C PCI devices |

ERROR: Could not open PawnIO, PawnIO initialization aborted

Full verbose log available upon request.
(OpenRGB was launched with --debug, and “Shared SMBus access” was enabled.)

Operating System

OS: Windows 11 x64
Privileges: Run as Administrator

Hardware Configuration

Component	Model / Details
Motherboard	MSI MAG Z790 TOMAHAWK WIFI (MS-7D91)
CPU / Chipset	Intel 14600K
RAM	2 × 16 GB Lexar Ares DDR5 6000 MHz
GPU	NVIDIA (NvAPI I2C interface detected)
Keyboard	Logitech G915 Wireless RGB
Other RGB software	None — only OpenRGB installed

Additional Notes

SMBus access works (GPU I2C successfully detected).
The Lexar DDR5 RGB controller is likely not yet supported by OpenRGB.
Willing to provide additional logs, I2C dumps, or perform tests if needed.
