I want to design a simple circuit which is interfaced to PC via USB. Say, for an instance a group of LED's, and I wan't to switch on/off each LED via MATLAB? Is it possible...please help me..........

very possible. The easiest by far is to grab a USB eval kit or
even better a USB DIO module like the DIO32 from
Accesio ( http://www.accesio.com/go.cgi?p=../usb-oem/usb-dio-32.html ).
That way all the hard part ( circuit and driver design ) is
already done and you can get on with what you really
want to do.

If you want to get your hands dirty, you may want to still
start with USB eval kit since that would give you the IC's
taht you need.
