usbhid's mousepoll parameter is setting all of the gaming mice I've tested to exactly 1/2 of the expected polling rate that I specify, but only if the gaming mice are using the ohci-hcd driver. To test polling rates, I use the evhz utility: http://web.archive.org/web/20060623094750/http://homepages.nildram.co.uk/~kial/evhz.c Here is an example using a Zowie EC1 eVo gaming mouse with usbhid.mousepoll=1: [ohci] From dmesg: [ 9998.795207] usb 7-3: new full-speed USB device number 2 using ohci_hcd From evhz: event3: latest hz = 500 (average hz = 500) event3: latest hz = 500 (average hz = 500) event3: latest hz = 500 (average hz = 500) event3: latest hz = 500 (average hz = 500) [ehci] From dmesg: [10217.625617] usb 2-1.1: new full-speed USB device number 5 using ehci-pci From evhz: event3: latest hz = 1000 (average hz = 1000) event3: latest hz = 1000 (average hz = 1000) event3: latest hz = 1000 (average hz = 1000) event3: latest hz = 1000 (average hz = 1000) My motherboard is an Asus Sabertooth 990FX/GEN3 R2.0, which uses the SB950 south bridge chip to provide USB. I've also tested a Gigabyte GA-990FXA-UD3 which uses the same south bridge chip and have the exact same problem.

Same here on GA-990XA-UD3 with kernel 3.12. After reading this i worked it around by plugging the mouse into an USB3 port, which uses xhci_hcd instead. So, how's it going with merging that patch from the mailing list ?
I too have the same problem with kernel 4.0.1. ehci-pci USB ports work correctly up to 1000hz whereas the uhci_hcd ones only go up to 500hz. Any chance this can be fixed?
Same problem here with kernel 4.0.1.
Any news there? It's already 4.8 and the bug is still there. I have mx518 and can't pass 500hz,

Just for completion and remembrance: https://www.mail-archive.com/linux-usb@vger.kernel.org/msg24948.html - this is what I was referring to.
