Better** to post more details of your problem keyboard and mouse (Make, model etc.). Are they wired or wireless? Do they appear as "working devices" in http://elinux.org/RPi_VerifiedPeripherals ? Try booting into NOOBS with just a "cheap & cheerful", basic wired keyboard + RCA video connection. (You don't need a mouse to navigate the NOOBS menu's, the tab & cursor keys should work too).Haswellpi wrote:I will now post a video

I don't think it's really a problem of "not enough power from usb ports". Unfortunately your "trouble-shooting" approach has not been systematic (eg. change only one thing at a time, record what happens - such as the LED behaviour like @Pi_Fanatic refers to, measure the testpoint volatage etc.)** Although you (eventually) stated that the keyboard & mouse "had" worked initially, without you checking them on another computer and a different keyboard or mouse (known to work, again on another computer) it's virtually impossible to tell whether one or other of those devices have "broken" and/or the Pi has been damaged somehow.Haswellpi wrote:How can i get enough power from usb ports??
Thanks to all
The text on the video was unreadable but if you are referring to the "fsck" error from your other post, I replied to that earlier and gave you the answer. Also I thought you said the composite video was not working yet you give us a video of a working screen.Haswellpi wrote:Also when i am trying to install raspbian on raspberry pi i get this error http://youtu.be/Z-b06qQPguQ

HaswellPi, you have asked this question a number of times and I think we are at a standoff here. You don't "Power up a mouse and keyboard", the USB ports either work or they don't and the USB ports not functioning is very rare. If you have a multimeter and a spare USB cable, you could cut a USB cable and test the voltages coming out of the USB port i.e. Plug the USB A Male end into the Pi USB port and then test the red lead against the red wire and black lead against the white wire. If the USB is functioning you should get a 5V or close to 5V reading from either port.Haswellpi wrote:How can i power up a mouse an keyboard? Thanks
