I made a kernel module for overclocking USB devices (gamepads, mice, etc.) (lemmy.blahaj.zone)

This DKMS module allows you to overclock some USB devices by overriding their endpoints' bInterval values in the device descriptors – if the device physically allows you to poll it at higher frequency and will give you more data.

Back on Windows this (with the same method) was rather trivial using the "hidusbf" program. And ever since moving to Linux I was pretty annoyed I didn't have a similarly simple enough way of doing the same thing. So basically I guess I had no choice but to make one.

And the module allows doing that for theoretically any USB device without patching and re-compiling the kernel. Installation instructions are in the README (there's .deb, .rpm and AUR packages):

So let me know what you think, and if you managed to overclock any gamepads or other devices, or want to try.

Personally only controllers (my own mouse and keyboard already poll at 1000 Hz, suffering from success...). I can't imagine it'd go too well with something like a drive xD It's also worth noting it only overclocks Interrupt endpoint, and not other types like Isochronous, since they're not used for input stuff and their bInterval values mean different things. But I wish I could find some other goofy device to try where there'd be a chance it could do anything other than breaking everything...
