USB is not a long distance system. Try shorter USB 2.0 cables.

i wanna connect 10meter usb extender to a 4ports usb hub. But it is not working because it said unknown device. It shows "Windows has stopped this device because it has reported problems. (Code 43)".
It is working fine if connecting 10meter usb extender to a mouse or keyboard. It just can't connect to a usb hub.
So is the power problem of the usb hub or i can't connect extender to hub?
