Mouse lag after upgrade. Setting polling speed does not help. [SOLVED]

Hello. I'm a happy Arch user since Jan 2016.
An upgrade that I did some fortnight ago caused a persisting issue:
My bluetooth mouse (Microsoft Sculpt mobile) lags irregularly and untolerably. Sometimes it's very smooth and sometimes lags are like 2-3 seconds.
Sorry if this post is a dupe but I didn't find anything other than tweaking `usbhid` options to use higher polling speed, which did no effect to my issue.
It only applies to latest two Linuxes from official repos I guess, because I have had no trouble on install (Jan 28)

Thank you.

Are you absolutely sure the behaviour is due to the kernel version? Eg. have you tried a downgraded kernel, linux-lts or a graphical live environment?

Thanks for the reply.
I'm unable to play with this Arch system as this is the one I use for work. So I didn't try a downgraded kernel or linux-lts.
I'm pretty sure my graphical environment has nothing to do with that as I'm using XFCE consistently and it didn't have major upgrades till recent when the issue was already present.

I've been able to solve the issue for some 5-10 minutes by plugging my bluetooth transceiver to another USB port (both ports are blue so I guess USB 3.0)

That's the exact reason why you should have the linux-lts kernel installed. And it's as easy as:

# pacman -Syu linux-lts
# grub-mkconfig -o /boot/grub/grub.cfg

Then at boot time choose which kernel to boot.

Sorry, I didn't mean to suggest the environment was the problem. Running a live Linux (with any graphical environment) could be an easy way to run an older kernel without modifying your Arch install.

Hey friend, you were pretty close
I wasn't a live environment but the VESA (or whatever it's called) driver: The mouse lag disappeared after I have installed `xf86-video-intel` (as I have an Intel integrated video card)
So, the `usbhid` module is not to blame

Thanks, but I'll stay with the mainstream kernel as much of Reddit reports `linux-lts` not being any more stable

I'm not saying you should switch to linux-lts, just that you should keep it installed as a backup. And even if it weren't anymore stable the odds that both kernels will be unbootable at the same time are much lower than just having one of them. (And as a redditor for 6 years I can tell you that it is not exactly the most reliable source of information.)
