I have found that, at last, the polling rate will be configurable for USB joysticks in 4.12 kernel:
https://patchwork.kernel.org/patch/9591909/

It seems to have been merged upstream, so, could that be backported to Pi's current kernel? It will be some time until we are at 4.12 as default, and the feature is interesting enough.
Also, it's a very simple patch really.

Thanks

@pelwell I've tested and 4.12 patch applies without much grief. Any objections?

Thanks for the backport! When can we expect the next rpi-update with this?

Should be in latest rpi-update kernel. Please test and close if happy.
