System won't accept my keyboard and mouse [Solved]

[AlveKatt]

I am running Linux Mint 17, Rosa.

 

My keyboard and mouse doesn't work once I get to the Linux Mint Login screen. It works fine in the Bios. UNLESS, unless I turn the computer off, turn off the power at the power supply, and then boot again. Then everything works as it should.

Well, it could be a bunch of reasons.

 

Did the keyboard and mouse work fine during the installation of the OS?

If so, I would try reinstalling the OS. Probably some files did not installed correctly.

Something like sudo apt-get update and sudo apt-get upgrade could also correct the problem (although I think the chance is low).

 

But if the mouse and keyboard did not work during installation, then they are probably not supported. 

 

Other possible (likely) problems:
- Some mouse/keyboards don't work very well with USB hubs. If you're using one, try to remove it and use the keyboard/mouse without the USB hub.

- It could be a USB driver problem. It can easily happen if your mouse and keyboard are connected to a USB 3.0. Install the proper drive for your motherboard and it should work fine. To do that, you can connect your mouse/keyboard on a USB 2.0 (yeah, I think that is the only reason usb 2.0 are still a thing. Drivers that do not install correctly).

Can you use ps2? if they work after restart it sounds like a detection or power issue which could go back to a usb driver issue in which case you can dind various how-tos about the internet to install/reinstall/update the drivers for the usb and probably the mouse and keyboard. 

You can try a re-install though and probably resolve it abit easier. the update command may help, just be sure the board is working when you run it, the upgrade will upgrade the entire OS so it may be abit useless since you most likely are on the newest version.

Sudo apt-get upgrade installed linux-firmware. I have a feeling it might be solved now. Thank you, I'll report on whether its actually solved tomorrow.

Computer booted okay this morning. Feels like it's too early to celebrate, but initial findings suggest it's fixed now. Need to boot it a few times to be sure. Do not feel like doing it ten times in a row though, I'll get back to you.

About USB 3 vs USB 2. There is not point in putting peripherals like Mouse, keyboard or even my Wacom drawing tablet in USB3 right? Unless I put them all in a hub so they use the same USB port... Might get an external WIFI-card though, then USB 3 should be useful, right? Only, maybe I really should get an internal, might get issues with drivers in Linux if I get an USB one?

Edit: Boot number two today. Turned it off when going to the store. Everything started okay.

If you solved the problem, it helps the forum by marking the post that solved the issue as “solved.” Thank you!

I wanted a few more boots to be sure. But the problem hasn't come back. Even after I plugged in the rest of my USB peripherals. (Webcam and Wacom Tablet.) But now I have marked the thread as solved. Thank you!

Yes, most peripherals won't gain any performance for using USB 3.0. But there are some which supposedly have benefit for using USB 3.0 (some high end keyboards and mouses). I don't really know if they indeed have better performance though. 

And yes again. Anything which purpose is to transfer data can benefit a lot from using USB 3.0.

So WIFI adaptors and HDs are a good example. 

 

But as long as you get something reasonable common you probably won't have any problems. Linux will take care of installing that driver for you.

In case it doesn't (depending on your distro and luck), nothing that the internet can't help you with in less than 5 minutes.
