Dell TFT - usb and card reader problems

* Power off the monitor
* Disconnect all cabling from the bottom and/or sides of the monitor (especially the power cord). Disconnecting the power cord releases all circuit latches "resetting" them
* Press and hold the monitor power button down for 5 seconds
* Reconnect only the monitor power cord and either the #1 blue VGA or #2 white DVI (not both)
* Power on the monitor
* The PC should already be on. The monitor should auto sense the #1 blue VGA or #2 white DVI. If it does not, press the Input Select button and change to #1 VGA or #2 DVI

Test the Card Reader and USB ports.
