Could you tell us specifically about the issue you're running into? Please reply here as well with the serial number of the affected Roku device. It can be located at the back or underneath the player itself.
My Roku keeps displaying the warming message "the usb does not have enough power for the device...". I am using the original adapter that came with the Roku. I have tried multiple outlets, multiple usb cables, multiple USB ports, and multiple TVs. The red light is not visible, but the white indicator on the front is and blinking. I have read numerous posts and I'm still unable to resolve this problem.
