I am trying to connect keyboard on my raspberry pi alongwith hdmi. But when i connect keyboard to the rpi, hdmi stops working and vice versa. But they both are working alone but not together. Any ideas how i can make them both work together.

This is my config.txt file and these are my current configuration for running hdmi on rpi.

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

uncomment this if your display has a black border of unused pixels visible

and your display can output without overscan

disable_overscan=0

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

#overscan_left=16 #overscan_right=16 #overscan_top=16 #overscan_bottom=16

uncomment to force a console size. By default it will be display's size minus

overscan.

#framebuffer_width=1280 #framebuffer_height=720

uncomment if hdmi display is not detected and composite is being output

hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

hdmi_group=2 hdmi_mode=16

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

config_hdmi_boost=4

uncomment for composite PAL

#sdtv_mode=2 #uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800

any thing i am doing wrong?? Any help would be appreciated.
