Fedora system detect usb, but it doesn't work in fedora softwares (please read details to understand)
Hi, I just installed korora which is a nice distribution based on fedora. I downloaded some others linux distros to test them with my usb (live). I did it until this problem happend, I don't know why. The issue is: The operating system detects my usb nevertheless fedora live usb creator and unetbooting doesn't detect it (also virtualbox)

USB is not detected img : 
Thanks in advance
Have you tried to first unmount the usb (not completely remove it or eject it, but unmount) and try again with such programs ? Virtualbox is a special case where you have to have installed the Extension Pack in order for USBs to be recognized and work properly. Also, I would try with an Official Fedora (or Spin) distribution. Better would be to report this problem in Korora's support desk.
Regards.
Thanks for your reply, but I tried it before. When I downloaded Korora, I wanted to try something else so I downloaded lubuntu. And it's worked perfectly before, I used fedora live linux ,unetbooting before and it worked!
