Actually, there were a couple of comments about this. I know, because I posted one of them, and just responded to another...
Actually, I haven't had any issues plugging USB 2.0 devices into USB 3.0 ports on my Ubuntu system. My Windows guest systems see those devices just fine. However, plugging in a USB 3.0 device into a USB 3.0 port doesn't work; it isn't seen by the guest system at all.
Fortunately, if your system has USB 2.0 ports, you can plug a USB 3.0 device into one of those and your guest system will see it. It just can't access it as quickly as if it were USB 3.0.
All of this is on my "Trusty" system on an HP Pavilion P7-1235. Your mileage may vary.
There is no support for USB 3.0, and more and more computers are only coming with USB 3.0 ports. Those are "invisible" to guest systems running under VirtualBox. Otherwise, it pretty much does everything I need it for (running Windows under Linux so I can run TurboTax and Garmin mapping software).

Considering that Java appears to be a flimsy screen door in any company's firewall, I would think that most SANE organizations would've started moving off of that platform YEARS ago...
It's my primary browser/E-Mail/Usenet client. Why install two products when just one will do?? It also takes up less resources as well.
The only issue I have is that a lot of Firefox extensions won't work in Seamonkey, and their authors don't seem terribly eager to support Seamonkey either. I used it in Windows, and now that I'm in the process of migrating to Linux (Ubuntu), I'm using it there, too.
