I finish my tests and the bug is already reported upstream
I build a new kernel with patch mention on #comment:13 and all works
fine, so the problem is with kernels > 3.14 . So will take time to fix
land into Fedora stable. I'm going try accelerate the process.
When I receive your email I tried out a usb pen and doesn't work , after
I go to VirtualBox -> main menu -> help -> check for updates , and
install new Oracle Vm VirtualBox extensions 4.3.14 , and usb start to
work, but kernel on host oops every to 2 seconds , without patch
I build a kernel  (if you want you may install it) which have the
patch to not spam dmesg . I verified these kernel oops are just
warnings and USB works without problem.
