Ok, so I got a toshiba Satego Laptop, and am currently running windows 7.
I have 2 problems, which I feel could be connected though : First I got a "USB Composite Device" on one of my USB hubs (its the only thing that shows on this hub, I'm guessing its something internal in the laptop). And this Composite Device power supply shows "unknown" when its activated, and 500mA when its deactivated. No idea what it is, tried uninstalling deactivating and everything I could think of.
Secondly when I transfer data through my lan network here (I use wlan on the Laptop) my USB mouse gets all screwed up, it lags and haggles, only moves every other second for a bit, makes it quite frankly unusable. My touchpad and everything elses continues to work fine though, its not the computer that has the problem.

Well thanks in advance for any help, bye

My guess would be that the laptop is not supplying enough power to the HUB, this results in the hub not functioning correctly.

Try using the HUB in a desktop with the mouse that is lagging. If the issue does not occur in a desktop, this means that the laptop cannot hold up the USB HUB .

You will need to use the HUB in another USB port. Most laptops have 1 USB 2.0 port which actually provides more power than the other ports which is just USB 1.1

Its not a HUB in a physical sense. It just shows up in the Device Manager as USB hub, its built in.
