USB devices not detected

Question

None of them seem to show up in lsusb. Neither my mouse nor any USB drives.

Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

But dmesg seems to detect them:

I was recommended to just reinstall Ubuntu, and USB devices worked after that, but they stopped working after I updated. I think I started having this problem after updating around last night, so all I can think of is that it's something to do with the update.

Solution

You might have been affected by this bug. Updating to a newer kernel may solve your issue.

1. Find your Ubuntu installation's architecture.
   Run uname -m. If it returns i386 or i686, then it's i386 (32-bit); if it returns x86_64 or amd64, then it's amd64 (64-bit).

2. Download the latest mainline stable kernel from here.
   In this case, you should download the following:

   linux-headers-3.19.3-031903-generic_3.19.3-031903.201503261036_ARCH.deb
   linux-headers-3.19.3-031903_3.19.3-031903.201503261036_all.deb
   linux-image-3.19.3-031903-generic_3.19.3-031903.201503261036_ARCH.deb
   

   Replace ARCH with the architecture found above (i386 or amd64)

3. Install the packages with sudo dpkg -i linux-headers-3.19.3-031903-generic_3.19.3-031903.201503261036_ARCH.deb linux-headers-3.19.3-031903_3.19.3-031903.201503261036_all.deb linux-image-3.19.3-031903-generic_3.19.3-031903.201503261036_ARCH.deb, again replacing ARCH with your kernel architecture

4. Reboot.

Could you update to the latest stable mainline kernel and try again? Download linux-headers-3.19.3-031903-generic, linux-headers-3.19.3-031903 and linux-image-3.19.3-031903-generic from here (for the correct architecture: if you've installed 64 bit Ubuntu, get the files ending in amd64.deb, otherwise, get the files ending in i386.deb). Then, in the terminal, install the kernel with sudo dpkg -i <the three files you downloaded>.

got something about "possibly missing firmware" >W: Possible missing firmware /lib/firmware/rtl_nic/rtl8107e-2.fw for module r8169 >W: Possible missing firmware /lib/firmware/rtl_nic/rtl8107e-1.fw for module r8169 >W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-2.fw for module r8169 >W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-1.fw for module r8169 And now I need to restart it seems

Try to install the linux-firmware package with sudo apt-get install linux-firmware, and if that does not work, try installing the linux-firmware-nonfree package too

Downloading the new kernel seems to have worked. And it seems I already have the stuff in linux-firmware.

He had already mentioned that it worked on a clean install of Ubuntu, but it broke after updating.

The problem is with my software rather than any specific usb device. And I already did reinstall, but everything stopped working again after an update. System profiler doesn't detect any USB devices either.

@zhongfu Thats why I told him to reinstall the upgrade or ubuntu to fix it. Please don't downvote

[zhongfu]

The problem is that he has already reinstalled Ubuntu, i.e. done what you suggested for him to do.

[Nived Kannada]

@zhongfu So if its not working. I don't know how to fix it. Just try reinstall drivers. or don't upgrade again. I prefer to download iso and install it
