I sometimes lose input from keyboards and mice input after resume

I have this laptop , and I have a problem with suspend/resume. Namely, sometimes (maybe 1/5 of times) after waking the laptop up from suspend, my keyboards (both on the laptop and USB keyboard plugged in), USB mouse, and trackpad will not work. However the screen continues working, and anything animated on the screen will continue moving, so I know it's a loss of input and not a general crash. The only way I'm able to recover is to hard reset the machine.

Has anyone else experienced this? I've not been able to diagnose the issue. What logs or tests should I look at to shed some light on this problem?

Your computer can run commands automatically before it suspends and after in resumes. Consider adding a post-resume script that will reload the USB kernel module.

I'm sorry I don't have more information. I haven't used suspend in a long long time. Good luck!

Re: I sometimes lose input from keyboards and mice input after resume

I have a solution that appears to be working. I installed a thing called systemd-suspend-modules from the AUR. It lets me designate a list of kernel modules to unload when the machine suspends and then reload when it wakes back up. My /etc/suspend-modules.conf is this one-line file:

ath3k btusb rtsx_usb ehci_hcd ehci_pci usbhid xhci_hcd xhci_pci
