Mouse lighting issue

I'm having a slightly odd issue with my mouse where it is 'stuck' in a lighting patten that I can't seem to edit at all (through Synapse or otherwise).

I can edit my keyboard lighting just fine through Synapse, but anything I try for the mouse has no effect (and Synapse has no idea that the below pattern is what is actually happening on the mouse)

Troubleshooting steps tried so far:
- different computer
- different USB ports
- uninstalling drivers and software

The lighting pattern (incase meaningful, timings are estimated, on both clickwheel and logo)
0.5 seconds white
0.5 seconds off
0.5 seconds red
0.5 seconds off
0.5 seconds green
0.5 seconds off
0.5 seconds blue
0.5 seconds off
...and repeat

Mouse is deathadder elite, was purchased yesterday, no noticeable damage to box, and works completely fine otherwise.

Any suggestions much appreciated!
