I'm trying to break this down further:
This block is the set of keys which I've included the byte output for in
a reply further back, repeated for clarity. This block is currently not
interpreted by the kernel as anything I guess due to the vendor specific
page:
0x06, 0x31, 0xFF, // Usage Page (Vendor Defined 0xFF31)
0x09, 0x76, // Usage (0x76)
0xA1, 0x01, // Collection (Application)
0x85, 0x5A, // Report ID (90)
0x19, 0x00, // Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage Maximum (0xFF)
0x15, 0x00, // Logical Minimum (0)
0x26, 0xFF, 0x00, // Logical Maximum (255)
0x75, 0x08, // Report Size (8)
0x95, 0x05, // Report Count (5)
0x81, 0x00, // Input (Data,Array,Abs,No Wrap,Linear,Preferred State,No Null
Position)
0x19, 0x00, // Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage Maximum (0xFF)
0x15, 0x00, // Logical Minimum (0)
0x26, 0xFF, 0x00, // Logical Maximum (255)
0x75, 0x08, // Report Size (8)
0x95, 0x3F, // Report Count (63)
0xB1, 0x00, // Feature (Data,Array,Abs,No Wrap,Linear,Preferred State,No Null
Position,Non-volatile)
0xC0, // End Collection
while the ROG key gives:

This block is functioning fine as a consumer device:
0x05, 0x0C, // Usage Page (Consumer)
0x09, 0x01, // Usage (Consumer Control)
0xA1, 0x01, // Collection (Application)
0x85, 0x02, // Report ID (2)
0x19, 0x00, // Usage Minimum (Unassigned)
0x2A, 0x3C, 0x02, // Usage Maximum (AC Format)
0x15, 0x00, // Logical Minimum (0)
0x26, 0x3C, 0x02, // Logical Maximum (572)
0x75, 0x10, // Report Size (16)
0x95, 0x02, // Report Count (2)
0x81, 0x00, // Input (Data,Array,Abs,No Wrap,Linear,Preferred State,No Null
Position)
0xC0, // End Collection
This block has I/O. 0x5D, // Report ID (93) is the LED backlight for the
keyboard. The Backlight controller I think writes back the input data.
0x06, 0x31, 0xFF, // Usage Page (Vendor Defined 0xFF31)
0x09, 0x79, // Usage (0x79)
0xA1, 0x01, // Collection (Application)

0x75, 0x08, // Report Size (8)
0x95, 0x1F, // Report Count (31)
0x81, 0x00, // Input (Data,Array,Abs,No Wrap,Linear,Preferred State,No Null

0x19, 0x00, // Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage Maximum (0xFF)
0x15, 0x00, // Logical Minimum (0)

0x75, 0x08, // Report Size (8)

0xB1, 0x00, // Feature (Data,Array,Abs,No Wrap,Linear,Preferred State,No Null

0xC0, // End Collection
I don't know what this block is. HID descriptors are a little confusing to look
at:
0x06, 0x31, 0xFF, // Usage Page (Vendor Defined 0xFF31)
0x09, 0x80, // Usage (0x80)
0xA1, 0x01, // Collection (Application)
0x85, 0x5E, // Report ID (94)
0x19, 0x00, // Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage Maximum (0xFF)
0x15, 0x00, // Logical Minimum (0)
0x26, 0xFF, 0x00, // Logical Maximum (255)
0x75, 0x08, // Report Size (8)
0x95, 0x05, // Report Count (5)
0x81, 0x00, // Input (Data,Array,Abs,No Wrap,Linear,Preferred State,No
Null Position)
0x19, 0x00, // Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage Maximum (0xFF)
0x15, 0x00, // Logical Minimum (0)
0x26, 0xFF, 0x00, // Logical Maximum (255)
0x75, 0x08, // Report Size (8)
0x95, 0x3F, // Report Count (63)
0xB1,
0x00, // Feature (Data,Array,Abs,No Wrap,Linear,Preferred State,No Null
Position,Non-volatile)
0xC0, // End Collection
It would be reasonably easy to have the kernel catch the Aura/Keyb-light keys
and divert those to control the keyboard LEDS I hope. A handful of keys don't
appear to have matching HID descriptors that I can see (mic-mute, screen-off,
fan, trackpad, plane-mode) so they likely need internal kernel calls?
Again, I'm willing to put in the work for this, including trying to get fan
control/performance mode or similar, if someone can mentor me.
