I am having trouble mounting my 16GB usb3.0 flash drive both on windows 7 and ubuntu 14.04.

Device doesn't show on fdisk or when I run lsusb.

This is what I get when I run dmesg after pluging it in. Any help will be greatly appreciated.

I don't know if it's related, but the first time I tried using it I experienced a crash on ubuntu.

  • for the error -62, in my case it was a USB printer that I was connecting to a USB port 2.0. it hinted that the usb cable could be bad, but when I connected it to the usb port 3.0 it worked (after I restarted the printer and after the second time I reconnected the cable on both the printer and the desktop)!

If your USB drive has problems on both Windows and Ubuntu and it's connecting/disconnecting/connecting/disconnecting/... all the time, it looks like your USB stick's control circuit has been busted.

To be absolutely sure:

  1. try another USB peripheral on the same port (Keyboard/mouse printer/...)
  2. Shut down the machine completely, remove all power & batteries, turn it back on for a second, re-insert batteries & power, turn on and try again

if 1 works and 2 fails, throw away the USB key and buy a new one.

  • Turned off for a while and it worked... I guess it was a hardware issue
