Hello,
a reason could be that the drivers for your stick are not included in the krenel of your OpenELEC. You can check this when logged in with SSH using:
lsusb - this shows the connected devices, here you should see your stick conected e.g. for my Freecom Stick(here recognized as WideView)stick:
#lsusb

Bus 001 Device 007: ID 046d:c71f Logitech, Inc. diNovo Mini Wireless Keyboard
dmesg | grep dvb - check if a dvb Driver is loaded, for my system stick is loaded

If your kernel does not include the first try the newest version of OpenELEC - actual 3.0.6 with kernel 3.6.11. If this does not help you have to compile a kernel including the Drivers for your stick
If the stick is present with loaded drivers and still causes problems try a bigger power-supply (e.g. for iPAD)
Best regards
