Got a creative zen, will charge from a laptop or PC via usb as normal, however, it wont charge from a powered USB hub (hub is USB 2). The little lightening bolt comes on when its plugged in to show that its connected but it has no charge in it up to a day later. The problem is the zen isnt mine and the person who owns it doesnt have a pc (I was going to give them the hub for charging the zen). The zen was bought SH so no warranty/receipt etc. Had a look on creative labs and couldnt find anything. Anyone?
