There's probably a better list for your question, since it really
concerns whatever gamepad that you have and the Linux kernel. I've
worked with a number of custom HID devices and haven't had an issue
with br. I'd suggest that you see how your gamepad performs with
desktop Linux. I would expect a similar report rate. My guess is that
there's a Windows device driver that enables the faster gamepad report
rate.

Also, the Linux input event system does try to suppress redundant
reports. I don't think that this is your problem from your trace.

I like the hidraw interface, but I'd check for a special command being
sent on Windows before changing anything.
