I have 3 USB3.0 ports and 1 USB2.0 port on my Laptop (w230st clevo). Unfortunately,the USB2.0 port does not work, despite being shown on lookup with lsusb, output shown below. Strange is, that lsusb shows 3 USB2.0 ports and one USB3.0 ports - so it could be that Ubuntu misinterprets the hardware. Another piece of information that I can provide is that bootable USB-sticks also only work with the USB3.0 ports, and if the bootable USB-stick is plugged to the USB2.0 port it isn't even shown in the bios bootdevice menu.

Here the output of lsusb:

At the moment I am kind of lost of how to best analyse the problem. I would like to know whether this is a hardware problem or one of Ubuntu.

Here the output of dmesg | tail right after plugging an usb-stick to the 2.0 port:

Note, I did not plug a bluetooth usb-stick related to the mouse, which connect directly to the laptops bluetooth.

Can you provide the output of dmesg | tail when you connect any device to the port? –  Braiam Oct 6 '13 at 20:11
    
I updated my post with the info you requested. Thank you for having a look into the issue. I must admit, I fear the port is dead, because even with a bootable usb-device plugged, that is not shown in the bios, whereas bootable devices are shown, when plugged to other usb-ports on the same notebook. –  cuichi Oct 7 '13 at 8:35
    
If you bootable media doesn't detect in Bios Boot Menu then how can you say that it is Ubuntu error! You should contact to your device manufacturer. Anyway I also want you to confirm. Run this command in terminal : sudo lshw -html > myhardware.html and then open it with any browser: firefox myhardware.html. Finally check the Version of all id: usb. Reply what you get. You can also post the output of this command: sudo lshw here. –  Saurav Kumar Oct 7 '13 at 9:37
    
@Kumar - exactly, that is my fear! However, my lsusb output suggests (if my interpretation is valid) that there are 4 usb ports. However, they seem to be identified incorrectly in terms of their version. I will post what you asked for in the main thread. –  cuichi Oct 7 '13 at 13:30
    
I have exactly the same problem here. Any progress? Can't boot in the bios on the USB 2 but they show in the lsusb –  Victor Oct 10 '13 at 8:11
