** Description changed:
- My laptop no longer recognises the usb storage devices; I tested with 3
- different devices (usb sticks, external HDD), on all 3 usb ports of the
- laptop (I think one of them is usb 3.0, the others 2.0).
+ 1. Normal boot up (either from the internal HDD or from the usb stick Kubuntu
Live Session)
+ 2. Mount the usb stick and then unmount (get the "Safely remove" message, but
do NOT remove the stick from the usb)
+ 3. Restart the laptop (let it boot-up using the internal HDD)
- I am sure it is not a hardware problem, as the BIOS can read the devices
- and I can boot from the usb stick.
+ Expected: next session should recognize USB devices (even if it won't
+ "see" the device I left in the USB, it should at least detect its
+ removal or other new devices)
- I read on a forum that the usb_storage kernel module may be required and
- so I loaded it manually (and I added it in /etc/modules), but it did not
- help.
-
- The /var/log/{syslog,dmesg,udev} files did not show any new lines when I
- inserted the flash pen into the usb port.
-
- The only package that I have installed that it could interfere with the
kernel abilities to detect the usb devices is virtualbox:
- root@zmb-laptop:~# apt-cache policy virtualbox
- virtualbox:
- Installed: 4.3.36-dfsg-1+deb8u1ubuntu1.14.04.1
- Candidate: 4.3.36-dfsg-1+deb8u1ubuntu1.14.04.1

- This may not help much, but I have the same Kubuntu 14.04 distribution
- installed on my office workstation (an intel i7 lenovo desktop unit) and
- it is successfully detecting and mounting the usb stick (it has the same
- 3.13.0-83-generic kernel version).
-
- The output of various commands that may help:

+ Actual: rebooting with the USB device still plugged in (after the
+ "safely remove" message) somehow disables all the USB ports of the
+ laptop; no matter if I remove the device afterwards, the USB ports
+ activity no longer gets detected until another reboot.
