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.

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.

You better reinstall to fix it easy, or just try installing a device manager from software center and there you will find the usb devices connected. Then click on one, and format it. Then you can simply start using it as usual.I've done it with the usb 3.0 pendrive I had. And now it works perfect.
