I installed virtualbox OSE on my ubuntu zaunty, and then setup two machines fedora & pcbsd. Now yesterday I checked that there are no usb detected in my VM. I yahooed (:)) the net for usb connect and found that there are no support for usb in OSE edition and you have to install non OSE edition for that.
Well I were believing that companies making open source software dont restricted their software for some feature (that is problem for non open source software like shareware/freeware for windows), But is seems Sun (or Oracle may be) not interested in providing full fledge open source virtual server solution. They behave same as their counterparts companies making shareware for windows. After all usb support in VM is basic need for any machine for today’s computers.
