Hi Michael and all: About this topic:
"Would you please tell us too, if there are changes programs code between VirtualBox 4.x and 5.x, because, without changes in my hardware host I can virtualize 64 bits O.S. in the firt (Actually I'm doing with Ubuntu 16.04 LTS), but in the second I can't (Not appear the options to virtulize 64 bits O.S.)" It is solved !, thank you very much to all. I did a new install of Ubuntu 16.04 LTS on my host (pc), and installed a VirtualBox version 5.024, and now there appear the options of new machine with 64 bits. I really sorry to bother you before with this. I'm going to probe the issue (USB recognize and able) too, and then I will tell you how is going on.
