Only have 3 on my laptop, one is constantly in use my a wireless mouse, then there's a keyboard, webcam, headset, game pad, ipod, external hard drive etc etc to be plugged in.
I bought a 4 port usb multi adapter, it seems to be utter shite, mouse and keyboard regularly stop working, ipod won't even sync or charge though it it would appear.
I know there's limitations to non-powered usb hubs, so should I buy a powered one, and if so will this actually make a difference, or am I just trying to send too much information down one usb port?
(Also I'm plugging a bunch of 2.0 devices in a 3.0 usb port so would getting a 3.0 device help?)
