6678	VBox Virtual Machine starup problem -> proposal  for  solution	MayBee		"Installing Ubuntu 10.04 all works fine. After working with the virtual Ubuntu several times, one day the virtual machine started no longer -> holds on 0%. I tried reinstalling of the guest system and the virtualBox, but nothing works. Then I realized that I have another external hard disc connected via USB at my USB hub.
As I disconnected this hard disc, the virtual machine starts and the virtual system boots. I think this has can be a good hint for this problem I found several times in the internet.

specific feature of the USB hard disc: it has two USB connectors for getting the level of electricity it needs

hopefully you can find the defect"	defect	closed	USB	VirtualBox 3.1.8	fixed			Linux	Windows
