What i mean is, after the system run for a while, when i plug in new usb things ( mouse and keyboard, external drives, usb key) it doesnt seems to detect anything plugged in… when the OS is freshly booted, no problem.
The motherboard is an Asus crosshair x570, maybe it would be a hardware issue? or is it a known problem with ubuntu 20.04?
Also check in the power control settings for your USB controllers. You can find it in directories like /sys/bus/usb/devices/usb1/power/. I can’t describe what they all do but look it up.
hum… update. didnt understand all the power setting for the usb, must look more into it.
did a lsusb while my keyboard and mouse wasnt working ( seperate usb keyboard/mouse combo that i didnt unplug so still worked) and my razer mouse and keyboard was still there. Just tried something, i logged off. as soon as i logged off, my main keyboard and mouse is responsive again.
