Why Ubuntu 14.03 and 15.10 don't support USB2.0?


Firstly, I had installed Fedora 20, and it worked smoothly in my
DIYed computer. My computer's mainboard is M5A97 R2.0, with 8-kernel
CPU. I had dual boot system, WIN7+LINUX, and I had not used Fedora for 3-4 months. Yesterday I opened fedora, but it was very very slow,
and I can not use root command, when I use $su , "input/output error"\ appeared. I formatted it and began to install Ubuntu 15.10,
but Ubuntu did not support all USB 2.0 interface in my computers,
it did not recognized keyboard and mouse inserted in USB2.0.

My win7 system has no problems. My computer's mainboard is M5A97 R2.0 and Bios is update. Who has the similar problems?

You may not get an answer.

If you wish to install the latest Ubuntu and then trouble shoot the issue we may be of some help. The best place to start is to find out what chipset is being used when you install or use a live distro that works.

I doubt that there is any moderately current Linux distro that doesn't support USB 1, 2 and 3. How do you know it doesn't recognize the devices?

To troubleshoot this, start by inserting them in different ports.
Also use the lsusb command - run it before and after inserting keyboard and mouse and compare.
The kernel message buffer should provide some information as well. For example, run tail -f /var/log/syslog to display kernel messages as they are generated, then insert the devices and see if there is any reaction.

Thank you @jefro and @berndbausch for yours answers, you are right.
The problem comes from the newest Asus bio update.
After I rolled back to old bios, everything was OK.
Thank you very much.!
