Seemingly unable to remap buttons on G903

[StelardActek]

I recognise this device isn't listed as supported, but I'm hoping I can somehow help get it supported. Changing the DPI definitely does work, but none of the buttons seem to be detected, and I get the following when I run logid as in a console:

$ logid -v

It occurred to me to try the device wired instead of using the powerplay mat. I get slightly different output, but button remapping still doesn't seem to work.
