Mouse scrolling slow at PC startup

Hi everyone,

I have this weird issue that I’m sure is a good explanation to. I cannot figure it out though. It’s 3 week old 60 v2.

When I start my PC, the keyboard always have some issue with the scrolling speed using the keyboard. It scrolls insanely slow. I have to restart the PC or re-plug the keyboard for it to go back to the actual expected speed. My settings are unchanged during this buggy phase vs. re-plugging or restarting.

Settings for reference:


Anyone experienced something similar?

I believe this GitHub issue is relevant to what you’re experiencing:


Maybe you can try using the reboot macro command to reboot the UHK, instead of rebooting the PC or unplugging the cable (I haven’t tried it myself yet). Hopefully that might be a temporary workaround.

This happen to my on every resume from sleep. I have to unplug and reconnect the keyboard to make it scroll at the regular speed.

I am running Arch Linux, happy to help fix this any way I can.

As far as we know, this is a linux kernel issue. It exhibits with uhk because we implement high res scrolling, unlike most mouses out there.

Benedek has written a patch and submitted to the kernel guys, but it hasn’t got much attention so far. Please, read [sleep-wake] Slow scrolling after wake up · Issue #1155 · UltimateHackingKeyboard/firmware · GitHub and help us push.

As an immediate workaround, you may set up a script on your linux that reboots uhk after a wake from suspend. Search for usb in firmware/doc-dev/user-guide.md at master · UltimateHackingKeyboard/firmware · GitHub . The macro command is reboot

Heya - I can disprove the linux kernel issue by contradiction there. I experience this on windows. (although I do use WSL if that for some reason has an effect)
